#13121 assigned Patch - Feature

Sat>IP client support

Reported by:	cg@…	Owned by:	Klaas de Waal
Priority:	minor	Milestone:	32.0
Component:	MythTV - Recording	Version:	Master Head
Severity:	low	Keywords:
Cc:		Ticket locked:	no

Description

The changes in the branch at https://github.com/cguedel/mythtv/tree/devel/satip add Sat>IP support to the backend. This allows the backend to use Sat>IP compliant networked tuners to record DVB-C/DVB-S/DVB-T programs.

This works relatively stable for me, however I can only test DVB-C on one network. Also, the channel scanner seems to be broken for this network, so I can't really test that.

EIT scanning is also working.

Support for DVB-S is certainly lacking, as the Diseqc configuration is missing altogether.

Also, this only implements the "Unicast Only Profile" as per the Sat>IP spec found at http://www.satip.info/sites/satip/files/resource/satip_specification_version_1_2_2.pdf. Multicast is not supported.

Thanks for supplying the patch; it is now in v32/master.

The patch has been updated for today's master and there have been some issues fixed.

Testing has been done with minisatip connnected to a DVB-S2 card in the same machine as the mythbackend and with a Telestar Digibit R1 box.

Satellite LNB selection via DiSeqC is defined in the Sat>IP protocol but is not yet implemented.

It is possible to use the same Video Source for a /dev/dvb tuner and for a Sat>IP tuner when they are connected to the same source.

The Sat>IP support is still a new and relatively untested feature; if anybody finds problems when testing this please add comments to this ticket.

Fix compiler warning

Fixed compiler warning about use of NULL instead of nullptr.

comment:6 Changed 9 months ago by Klaas de Waal

There is an issue with Multirec and EIT on the SatIP tuner. This can be avoided by disabling Multirec. To do that set the "Max Recordings" to 1 and uncheck the "Schedule as Group" in the Input Connections dialog of mythtv-setup.

comment:7 Changed 9 months ago by Mike Bibbings

Klaas,

In mythtv-setup Capture Card for Sat>IP I think an "Enable/Disable? EIT" checkbox is required. I ran a quick test with 4 x DVB/S2 tuners setup in minisatip and EIT processing was continuously running on all 4 tuners.

Whilst on the subject of eit, does "SATIP" need to be added in https://github.com/MythTV/mythtv/blob/master/mythtv/libs/libmythtv/tv_rec.cpp

void TVRec::CloseChannel(void)
{
    if (m_channel &&
        ((m_genOpt.m_inputType == "DVB" && m_dvbOpt.m_dvbOnDemand) ||
         m_genOpt.m_inputType == "FREEBOX" ||
         m_genOpt.m_inputType == "VBOX" ||
         m_genOpt.m_inputType == "HDHOMERUN" ||
         CardUtil::IsV4L(m_genOpt.m_inputType)))
    {
        m_channel->Close();
    }
}

Klaas,

Just tried DVB-T/T2 UK Freeview and it basically worked, although the "SETUP" messages are out of specification (minisatip does not seem to care), a couple of examples:

In 8cf47d3c2c/mythtv:

Sat>IP client support

First version of Sat>IP client support.
Tested with DVB-S/S2 but not with DVB-C and DVB-T/T2.
DVB-S/S2 is tested with minisatip and TELESTAR Digibit box.
LNB selection with DiSEqC is not yet supported, only direct LNB connections.
Channel scanning works although less reliable than with /dev/dvb tuners.
EIT does work and making recordings does work. Live TV can be an issue.

Klaas,

mythconverg database schema update is required to add SatIP Recorder to profilegroups with associated entries in recordingprofiles otherwise mythbackend reports errors like :

Jul 17 11:20:53 2004-satip mythbackend: mythbackend[5769]: E Scheduler tv_rec.cpp:4159 (LoadProfile) TVRec[1]: Profile 'Default' not found, and unable to load fallback profile 'Default'.  Results may be unpredicable

Manually adding the following to the database stopped the error messages above.

direct to database INSERT INTO profilegroups SET name = 'SatIP Recorder', cardtype = 'SATIP', is_default = 1;
Note the id created in this case 19
INSERT INTO recordingprofiles SET name = "Default", profilegroup = 19;
INSERT INTO recordingprofiles SET name = "Live TV", profilegroup = 19;
INSERT INTO recordingprofiles SET name = "High Quality", profilegroup = 19;
INSERT INTO recordingprofiles SET name = "Low Quality", profilegroup = 19;

see dbcheck.cpp dbver == "1339" for an example using Vbox

$SCHEMA_VERSION in mythtv/binding/perl/MythTV.pm and mythtv/bindings/python/MythTV/static.py will also need updating to next schema version.

Mike,

Thanks for the testing and for the tips. Expect fixes in the near future.

Issues not solved yet:

DVB-T2 tuning parameters
Recording profiles (was this not something from the PVR150/500 days, setting MPEG encoding parameters?)
MPTS full TS recording; described in the Sat>IP protocol but not yet implemented.

As yet untested:

DVB-C with minisatip

There are also still some stability issues with the TELESTAR Digibit satellite box.

Hi Klaas,

Hi Mike,

The above patch does solve a stability issue that came up when stress testing with a local DVB-S minisatip and a real networked Sat>IP box, also DVB-S.

However, your DVB-T2 scanning crash does look different. The plan is to reproduce this by attaching a MyGica? USB stick to a RPi3 and run minisatip on that. I do not expect that the hat does make any difference.

N.B. If there is any special incantation for the minisatip that you use please post that also.

Hi Mike,

Thanks for testing, looks like this is the same crash as before. So the discarding of old packets does not solve it, only makes the problem less frequent. Looks like a concurrency/locking issue as valgrind does not show anything.

Other bugs that are still present:

When configured with a single tuner instance and Schedule as Group disabled, then the backend crashes on EIT when the single tuner instance is closed. This is accompanied with Qt error messages about doing things in the wrong thread. Removing SATIP from the close in tv_rec.cpp, or having at least two tuner instances, does fix this for now.
Channelscan timeouts while actually finding all the channels.

Have been testing with minisatip and DVB-C and that works OK.

To be continued.

comment:29 Changed 8 months ago by peper03

Hi Klaas,

I had a bit of time to play around with this and immediately hit the two bugs you mentioned.

I've not managed to find a solution to them but thought I'd add what I've found so far:

The crash appears to be because SatIPChannel::Open is called in ChannelBase::CreateChannel? via TVRec::CreateChannel? at start-up in the main thread, but SatIPChannel::Close is called from the TVRec thread when the recording. This is what is causing the error messages about the wrong threads and appears to be what is leading to the SIGSEGV.

ChannelBase::CreateChannel? almost immediately closes the channel if it's DVB, HDHOMERUN or a V4L card, but not if it's SatIP. Adding SatIP here stops the recording even starting and I haven't had time to investigate why.

Regarding the channel scan, I'm not sure if it's the same issue you are seeing but I had to tell it to use only DVB-S instead of DVB-S2 before the scan would work. The DVB-S2 channels were still found and a brief look in Wireshark seemed to indicate that MPEG-TS packets were being received when DVB-S2 was selected but nothing appeared in mythtv-setup and it timed out on the first transponder.

comment:30 Changed 8 months ago by Klaas de Waal

Hi Richard,

Thanks for looking into this. You are completely right about the bits in ChannelBase?, I had overlooked this. Getting the recording to start again after the channel has been closed in ChannelBase? is being fixed.

What is still going wrong in the channel scan is timeouts. They are almost all caused by, after doing the tuning, receiving a PAT from the previously tuned frequency. Tuning is complete when all PMTs of all channels have been received and this then never happens. How to filter out the packets from the previous frequency is still an issue. One possibility is to check more on transport ID if that is known, but this is a biggish change to the common code and not limited to SatIP.

About DVB-S/S2, in the "Full Scan (Tuned)" you have to specify the delivery system and the other tuning parameters of the initial frequency you want to start with.

Such a high number of pids only happens with channel scanning
when the PMT pids for all channels in the PAT are selected.
Testing with hardware Sat>IP box, the Telestar Digibit R1, shows
that this box becomes unhappy when the number of pids is too large.
The software minisatip implementation does not have this limit.
Note that the limit for the number of pids in the DVB code

Current status:

Does NOT support DiSeqC yet
Supports channel scans
Tested with minisatip (DVB-C/T2/S/S2) and with the Telebit Digibit R1 box (DVB-S/S2)
No crashes observed for some time now

Implementation details that might be improved:

Open/close code. Channels are always kept open because opening and closing gives all kinds of errors.
Reducing the RTP packet processing interval from 200 to 20 ms does fix a problem with missing RTP packets in MPTS recordings but there is no logical reason why this should make a difference. A possible reason can be the implementation of the underlying packetbuffer code because random numbers are used to identify packets and there is always a risk of collusion when storing a large number of packets.
Channel scans work OK but sometimes the PAT of the previous transport is processed. This does cause a timeout but the scan results are OK. The difficult part is here that MythTV assumes that as soon as a tuning command is given that everything that is received after that is from the requested frequency. This is not really true in networked environments where packets are buffered. One possible solution, which would improve scanning for all tuner types, is to filter on transport ID when that is known. This requires storage of the transport ID in table dtv_multiplex and it somehow changes the concept of tuning from tuning to a frequency into tuning to a transport ID.
Tuning timeout default values are quite high and are correct for DVB-S/S2 but could be reduced for DVB-C and DVB-T2. The actual values can of course be configured in the Capture Card page of mythtv-setup.

I have tried a Telestar Digibit Twin but could only get one input to work and then with some packet loss. I have posted some log fragments in https://forum.mythtv.org/viewtopic.php?f=3&t=4102. It looks to me like the box is defective so I am not posting here as a fault. I will return it in the next few days. I can supply more log info if you think it is a genuine bug rather than defective hardware.

comment:39 Changed 5 months ago by jksj461

Testing with a Digibit R1- produces good results with 2 active inputs. Log shows good quality recordings with some but low packet loss

tv_rec.cpp:825 (FinishedRecording) TVRec[3]: FinishedRecording(65791_2020-11-21T00:05:00Z) good recq:<RecordingQuality overall_score="1" key="65791_2020-11-21T00:05:00Z" continuity_error_count="10" packet_count="19911688" />

I use a remote frontend so the network may be busy occasionally. If I up the number of inputs in use to 3 and add EPG, noticeable glitches appear on the display about every 10 mins. My question is have you tested using the standard firmware in the Digibit box :- Firmware Version V1.25.0.157 (30-03-2016 17:48) or are you using https://github.com/perexg/satip-axe.

I note that satip-axe is an implementation of minisatip which supports TCP streaming. If I switch to this firmware would the mythtv client work with TCP streams and do you think it would be a sensible solution.

comment:40 Changed 5 months ago by Klaas de Waal

I have not changed the firmware in the box and it is indeed "Firmware Version V1.25.0.157 (30-03-2016 17:48)". I have tested with two inputs simultaneously and as noted, this works OK.

However, I found a correlation between "Sequence errors", indicating RTP packet loss and consequently continuity errors, and EIT "write to disk" actions. This could be the cause of the periodic display glitches.

MythTV only supports UDP at the moment. Minisatip can do both UPD and TCP and maybe going TCP is the way forward, but for the moment the plan is to check the UDP packet handling.

comment:41 Changed 5 months ago by Klaas de Waal

Testing with the SatIP box the "Sequence errors", other than those that appear after tuning to a new channel, are almost all gone when the UDP kernel buffers are increased from 256kb, the default on my system, to 4Mb.

This can be effected with the following commands:

$ sudo sysctl -w net.core.rmem_max=4194304
net.core.rmem_max = 4194304
$ sudo sysctl -w net.core.rmem_default=4194304
net.core.rmem_default = 4194304

Investigation shows that the data is not lost in satiprtsp.cpp; all packets that are received from the UDPSocket are stored in the buffer and retrieved from the buffer without loss.

There are also no lost packets at the interface level; the network driver has no errors and network statistics do not show lost packets.

Therefore all packets are lost in the UDP buffers; the packets are simply not read on time by MythTV. This is demonstrated by the output of

cat /proc/net/udp

of which the last column is the number of packets lost.

Increasing the buffer size does give more latency. A full transport stream from a satellite is about 40Mbit/second which is 5Myte/second, so 4Mb buffering is 800 milliseconds.

I do not know how much buffer memory is used by the /dev/dvb/adapter*/* drivers but mythtv is capable of reading all data from these devices without loss.

Using TCP instead of UDP will not solve anything as the packets are not lost at the network level. TCP allows flow control between MythTV and the SatIP box but the SatIP box will be less capable of buffering the stream than the MythTV PC is.

Note that usually the PID filtering is done by the SatIP box; only when the number of PIDs is more than 30 the full transport stream is received. This is the worst case situation and this can happen with channel scanning on some streams. Normal recording always uses PID filtering by the SatIP box and then the 4Mbyte buffer should be big enough for perfect recordings.

comment:42 Changed 5 months ago by Klaas de Waal

Increase UDP buffer size for Sat>IP

Try to increase the UDP buffer size for reading the Sat>IP RTP streams to 8Mbytes (decimal). A log message is given when the system maximum only allows for a lower value. Change log messages to have only the cardid and not the device name on each message. This leaves more space for the actual message text.

Apologies I had not noticed that you had already posted on the benefits of increasing the UDP buffering. Having increased the buffering and taken f0c708a89a3b762fa3ccbe3d8ccede7745000649 the system is performing well. There was a bad patch yesterday when :-

continuity_error_count="4409" packet_count="21125940"

This bad patch occurred in the last 5 minutes of the recording on BBC One HD - in the overrun time (in the 5 mins after the recording was scheduled to finish). It occurs to me that this was because 'schedule as group' is the default settings in mythtv-setup. So a new recording had been started in parallel on that tuner while the old one was completing its overun time.

I have now removed schedule as group from all the capture card inputs which I think will improve stability.

According to the 'monitor' page of the Digibit, normal HD channels show average rates up to 10000Kbits average. However I am now running

SatIPSH[6](uuid:3eec0475-c365-44e7-bf7c-6d53b0daf8e4:DVBS2:1): Tune url:rtsp://192.168.0.44:554/?fe=2&freq=10847.00&pol=v&ro=0.20&msys=dvbs2&mtype=8psk&sr=23000&fec=34&plts=auto

is showing 50000Kbits average. The BBC One / Two HD mux seems to go straight to 50k independently of how many channels are being viewed.

I have now ditched my USB tuner and am using 3 inputs from the Digibox and it is working great including EPG many thanks.

comment:45 Changed 5 months ago by Klaas de Waal

Thanks for reporting back.

About the UDP buffer size. I've looked in the HDHomeRun library and there the UDP buffer size is set to 1024x1024 bytes, the actual value depending on the net.core.rmem_max value of the system. Note that it overall saves memory if you only set the net.core.rmem_max value and not the net.core.rmem_default because MythTV only extends the buffer size for the socket that is actually used for the video data stream. There is also a socket for the control data and the buffer size of that socket does not need to be changed.

I've looked into the "bad patch" problem and this is caused by the multirec feature not yet being implemented completely. What happens is that when your second recording starts the box is tuned again, on the same channel. This causes the disruption in your first recording. The correct behavior is to recognize that the channel is already in use and that it is already correctly tuned so the tuning can be skipped. This is how it is implemented for the /dev/dvb/adapter*/* devices (PCI/PCIe, USB) and this is also how it should be done for SatIP.

About the bitrate of the incoming stream. The code is now such that when more than 32 PIDs are requested the full transport stream is received. When there are less PIDs requested then the Sat>IP box is doing the PID filtering so then you only receive the PIDs that are needed. This is done because the Digibit R1 box effectively dies when your request more than 36 or 37 PIDs. The minisatip software, running on a PC, does not have this limitation but we write software for the worst case situation. Still to investigate why recording a channel on the BBC One/Two? HD mux requires so many PIDS that it needs to receive the full transport stream.

So connected all 4 inputs to the LNB and ran the system with only one recording allowed per card. This fell over at the transition time 9 pm again with lots of drop packets. A log is attached - it may be noteworthy that there is no tuning attempt for the program Harlots at 9 pm it must be trying to attach to an existing stream. Restarted the backend after 4 mins and it did the same thing again straight away ... mystified. Went back to my original configuration 3 inputs with two recordings allowed on the first. Seems bomb proof have been soak testing it ever since wth every sort of transition I can find between one or two recordings on the first tuner.

Log file added to attachments - apologies seems to have been attached to previous post? Just incompetance.

Again thanks for testing!

The latest update, commit f5e0fc0cf812b7615d571ef217e50229301bd5ef, skips the tuning part if you have a second recording on the same multiplex and thus avoids the "Sequence error" and the associated packet loss.

Next step is that the SatIP implementation will be restructured along the lines of how the HDHomeRun support is implemented. This is a comparable device, with four independent tuners and use of UDP packets for the video streaming. The HDHomeRun works OK with only a 1Mbyte UDP input buffer (instead of 8Mbyte) and it does not do extra buffering at the input. The current SatIP implementation is largely inspired by how it is done for Ceton and IPTV.

This should fix the remaining issues:

inefficient/slow due to buffering all received input data
allow to close the input device when not in use
allow restart of the backend

The HDHomeRun works OK with only a 1Mbyte UDP input buffer (instead of 8Mbyte) and it does not do extra buffering at the input. The current SatIP implementation is largely inspired by how it is done for Ceton and IPTV.

Klaas, FYI, I had a serious problem this past summer with frequent corruption in most recordings. With help, I traced the problem to lack of buffer space for my HDHR and Ceton tuners. I suspected a Linux kernel change was to blame as I'd never had the problem before and I don't believe the MythTV recorders had changed. Regardless of the cause, I raised my HDRingbufferSize setting to 75200 to get rid of the corruption. I have plenty of memory in my backend so I didn't spend any time backing that value down to see how low it could go without causing the problem.

Do the SatIP devices support TCP? From what I have gathered from other, HDHR users, using TCP does not have the same buffering problem and is also the recommended, access method from SiliconDust?. If the SaiIP boxes support TCP, you should consider using it, at least optionally.

mythbackend version: (HEAD detached at 7de9c58ad4) [v32-Pre-1753-g7de9c58ad4] www.mythtv.org

Had faultless recordings for the last 4 weeks until last night. I think that attempting to record more than one program on the same mux causes tuning problems where only a single channel is allowed. The above condition is unlikely to occur within my configuration so the above failure may be the only occurrence within the period. The issue arises probably due to me over constraining the configuration to get deterministic behaviour. I allow two simultaneous recording off the first mux and constrain the rest to one. This normally works fine as BBC1/2 HD are the lowest channel numbers and are normally allocated to this first mux. In the case in question the first mux was already allocated. Do you recommend me setting Schedule as Group for all tuners or setting max recordings to 2 for all tuners (which do you use).

It could be that your SatIP box has become unhappy. I have that incidentally when testing and then I reboot the box with the web interface.

I generally have the "Schedule as Group" enabled and then virtual tuners are created when needed. This does not change the load on the SatIP box that much, only a few additional PIDs are selected. There is a switchover point when more than 32 PIDs are selected; in that case all PIDs are received and all PID filtering is done by software somewhere. Note that this can already happen with a single channel, e.g. channel 101 "BBC One London" wants 36 PIDs.

When I test this with the Raspberry Pi 3B then it can get overloaded especially when it is doing EIT on the second input, which can also need the full transport stream. On a computer with a real 1Gb/s network interface this should not be a limitation.

In your configuration, with (IIRC) a number of inputs configured all to receive the same satellite, I would connect all inputs to the same video source, select "Schedule as Group" on all inputs and let the system figure it all out.

Thanks changed to use "Schedule as Group". Can't currently break it so great!. Currently trying to learn enough python to reset the Digibit when the backend is shutdown.

comment:53 Changed 2 months ago by jksj461

Just updated current master from v32-Pre-2005-g4ce4d36b2b to v32-Pre-2255-g37ef3848bd .

The first recording attempted was 30 mins but only the first minute was recorded.

Attempting other recordings showed the same problem. This is my production system so had to revert straight away. There is nothing obvious the system was looking for the recording to end at the expected time

Presumably the recent timer changes in Master have affected the sat-ip recorder.

Note that the input lights on the Digibit appeared to being extinguished much earlier than normal releasing those inputs. So time may have been affected in other ways than just recordings. Cannot be sure of this as I don't fully understand the normal behaviour, will attach log.

I can confirm that with today's master Sat>IP is failing. Version 86d05b6d2c which is from 29 days ago, so before the std::chrono update, is still OK. I will look into this.

comment:56 Changed 2 months ago by jksj461

Thanks for the quick fix much better but I had a zero byte recording for the first time ever using sat-ip when twp programs started at the same time. May be just a coincidence will test more in the morning.

I note that tuning fails at 21:00:04 implying that the timeout period is very short. Posting full log.

Having checked I note that 4 sec is the timeout setting. Looking back in the logs can certainly take 3 when multi recordings happen. Will test this morning.

14/02/21 09:30 Just started 4 simultaneous recordings, no issues and all happened in 1 second. Will test more leaving a couple of hours between events.

Failed Recording noting short timeout

comment:57 Changed 2 months ago by Klaas de Waal

Done some testing, 3 times two recordings starting at the same time, and they are all good.

Your failing recordings seem to be on TVRec[2], so the second tuner. Maybe this tuner currently does not work at all anymore. It could just be that everything is OK again after a reboot of the Digibit. Can you please try that?

Not really relevant to your recording problem, but your log format is rather different from mine. This is from your log:

Feb 13 20:59:40 tv mythbackend: mythbackend[8076]: I CoreContext recorders/satiprtsp.cpp:405 (timerEvent) SatIPRTSP[5]: Sending KeepAlive timer 6

This is a similar message from my log:

2021-02-14 14:07:01.713803 I [380058/380058] CoreContext recorders/satiprtsp.cpp:405 (timerEvent) - SatIPRTSP[11]: Sending KeepAlive timer 2

And this also with the latest, c64556b924.

That looks like the difference between logging to syslog/systemd and logging to a logfile.

Zero byte recording:- Seems to have been a one off, I have been testing and cannot repeat the issue, so many thanks.

I have been recording SAT>IP with MythTV for several years now by manually putting URLs into the database using IPTV (FREEBOX) tuners as per https://www.mythtv.org/wiki/SAT2IP_players_as_capture_cards.

It is good to see real SAT>IP support arriving for v32, and I thought I had better test it to make sure it was going to work for me. I have set up a new PC using the old motherboard from my mother's MythTV box, put Xubuntu 20.04 on it and installed v32 from the PPA.

For my current production system I am using minisatip on the same box as my main MythTV system, which has a TBS6909 8 tuner DVB-S2 card and a TBS6209 8 tuner DVB-T2 card. Mythbackend directly uses 5 of the TBS6209 DVB-T2 tuners for the 5 DVB-T muxes available here in New Zealand, and my MHEG5 EPG gathering uses one more of the DVB-T2 tuners, leaving two DVB-T2 tuners for minisatip. One of the TBS6909 DVB-S2 tuners is used for OpenTV format EPG gathering and the other 7 DVB-S2 tuners are used by minisatip. Minisatip uses my Sky NZ satellite card to decrypt my pay TV channels via Oscam. My mother's MythTV box also connects to minisatip to record Sky NZ channels.

On the new test PC, I created two sources, one for DVB-T and one for DVB-S2. I created two SAT>IP tuners, one for each source, and tried channel scanning. Scanning on the DVB-T tuner worked fine and I was able to record from the channels it put in the database. However, when I try to scan using the DVB-S2 tuner, I immediately get a popup error message "Error parsing parameters". I used Wireshark to check for traffic to minisatip, and the error was occurring before any packets were sent. I tried a number of different combinations of scan settings to see if that would help, but I got the same error each time. Then I deleted all sources and tuners and started again with only one source for DVB-S2 and one DVB-S2 SAT>IP tuner. But I got exactly the same error message.

MythTV Version : v32.0~master.202102151820.e787645fd9~ubuntu20.04.1 MythTV Branch : master Network Protocol : 91 Library API : 32.20200101-1 QT Version : 5.12.8 Options compiled in:

Klaas: If it is any use for your testing, I should be able to make my minisatip available for Internet connections - but that would require that connections came from static IP addresses that I could whitelist in my router. Leaving completely open ports to minisatip would not be a good idea. I have a fibre connection with 1 Gbit/s downstream and 500 Mbit/s upstream and my ISP's international bandwidth is good.

I might just take you up on that offer when things get difficult...

But first check the setup for the channelscan. The error message indicates that the tuning parameters are not filled in. Configuring his is the same for Sat>IP and for conventional satellite tuners, but it is different from how it used to be a few MythTV versions ago and it is not as user-friendly as it could be.

When you are in the Channel Scan page you have to select Scan Type. Select Full Scan (Tuned). This requires that you know the tuning parameters for the first multiplex. Press right arrow to get to the window to fill the tuning parameters, as described here: https://www.mythtv.org/wiki/Channel_Scanning#Full_Scan_.28Tuned.29 Press the left arrow to get back to the Channel Scan page. Then one choice down to the Scan button and do the scan. This should now work.

If you are happy with the scan then put the frequency of the initial transport in the Video Source. This frequency, and the tuning parameters of that transport, will then be the default the next time you do a Full Scan (Tuned).

If this fails then please post the command sequence/configuration/version for minisatip so that I can try to reproduce the problem.
