#6697 closed defect (fixed)

Initial tuned scan does not insert channels for new multiplex

Description

May be a new regression since r20770 (see my other ticket #6689). Currently running r20830.

When starting with a clean DB and no existing mux information, a tuned scan to a new mux will discover channels, but will not insert them.

Carrying out a subsequent scan of the individual mux will find the channels again, and will this time insert the channels into the database, but not correctly.

The scanner inserted as many multiplex entries into dtv_multiplex as there were channels discovered in the scan, and all were given a NULL networkid.

All channels added were associated with the first mux added to the dtv_multiplex table, and all had no default_authority value added.

After existing the scanner (entered via the Input Connections page) and navigating to the Interaction between inputs page, the value of the Input Group 1 field was automatically changed to "HDHR_/dev/dvb/adapter0/frontend0" instead of the normal "Generic". The Input Group 2 field was not touched.

Starting mythbackend after the scan of the mux gave the following warnings:

2009-07-08 05:25:13.038 DVBChan(1:/dev/dvb/adapter0/frontend0) Warning: Unsupported bandwidth parameter.
2009-07-08 05:25:13.039 DVBChan(1:/dev/dvb/adapter0/frontend0) Warning: Unsupported hierarchy parameter.
2009-07-08 05:25:13.963 DVBChan(2:/dev/dvb/adapter0/frontend0) Warning: Unsupported bandwidth parameter.
2009-07-08 05:25:13.964 DVBChan(2:/dev/dvb/adapter0/frontend0) Warning: Unsupported hierarchy parameter.
2009-07-08 05:25:13.982 DVBChan(3:/dev/dvb/adapter0/frontend0) Warning: Unsupported bandwidth parameter.
2009-07-08 05:25:13.983 DVBChan(3:/dev/dvb/adapter0/frontend0) Warning: Unsupported hierarchy parameter.

A single DVB-T card was configured for 3 multirec recordings. LiveTV is not tuneable for these new channels and EIT collection does not work.

The attached log (-v channel,channelscan,siparser) contains the initial tuned scan and subsequent scan from single mux.

Amazingly, I see this exact behaviour with Mythtv as shipped on Mythbuntu 10.4. So this should no be closed.

Mythbuntu shipped with a pre-release of 0.23. It's been reported fixed in 0.23.1 or trunk.

Anon, if you see this issue with trunk then open a new ticket with all the relevant details and full logs.
