Description (last modified by Janne Grunau)

Original issue solved!

Symptom: Mythtv-Setup scan for digital cable channels returns no channels on ATSC (QAM256) scan, digital cable feed.

Fedora 5 Kernel 2.6.17-1.2174_FC5 pchdtv HD3000 using cx88_dvb driver from above kernel mythtv version: Library API version: 0.20.20061213-1 (SVN 12265)

The foregoing says it all...scanning finds no digital streams. The hardware works, just not in myth. It used to work, but no longer does. Something wrong with the chann el tuning parameters.

Scan command used was: atscscan -a 0 -P -A 3 -U us-Cable-Standard-center-frequencies-QAM256 (Frequency list

from 513 to 855 MHz.)

This gave 454 digital streams: ~/.azap/channels.conf is attached. Log output for 'mythtv-setup -v record,channel,siparser > mythset.txt'attached as is a mysqldump of dtv_multiplex and channel tables. NOTE: there are NO channels for sourceid 2.

Output of "mythtv-setup -v record,channel,siparser", missing. Reopen after attaching log. thx.

Also is this svn head or 0.20-fixes branch?

Re-opening. Have twice attempted to attach the requested log, but the log exceeds the allowable attachment size. Hopefully danielk received the copy sent to him directly. Please advise.

This is SVN head (12265 I think). FE/BE on same box. HD3000 card working properly. In the meantime, another clue: Doing a channel scan, in Input Connections with the 'Unencrypted channels only' checkbox *cleared*, produces a 'good' scan: dtv_multiplex is populated, as is channel...of course, the channel table now includes all 454! digital streams. After deleting the unwanted channels, system is back to operating the way it did before Rogers Cable decided to move some channels...

As noted, import of channels.conf still fails. Since opening this ticket, 2 other instances of this failure mode have been reported to me directly.

I just attached a patch that allows scanning for non-encrypted channels only. It looks at the stream content rather than the mere presence of CA tables.
