I have an R5B7 system that's been upgraded to SVN revision 10010 (previously 9999 and 9846 before it). While troubleshooting an unrelated issue, I deleted and re-setup the capture card and data source. When I ran mythfilldatabase my channel list was messed up. To make a long story short, 5 of the 78 channels had a freqid that did not match the channel and the rest had 0. Manually changing the freqid to the correct channel number then running mythfilldatabase --refresh-all seemed to get the channels back in order, but I can't watch LiveTV.

The card is setup correctly because I can record programs via the program guide. The capture card recording settings are the same for default recording (works) and LiveTV (fails). When I try to watch Live TV I get the following error repeated many times in mythbackend.log:



I'm not terribly worried about it since I rarely watch LiveTV, but I'd like to get everything in working order again.

Go to:

make sure that all the "channum" fields are filled in.

They are and in fact were throughout all my troubleshooting. Once I entered the "freqid" of each channel they started showing up in the correct spots and with the correct logos. However, now recording programs works where LiveTV does not: same recording settings, same capture card, etc.

Update: I went back into mythtv-setup and changed the channel that it should try to go to next time LiveTV came up. Apparently when the channels were bad it was left on a bad channel number. Changing it to a good number made LiveTV work again.
