[mythtv-users] Problem tuning one channel, rest work.

[Greg Grotsky]

So, I recently started having a problem with tuning FOX on my myth machine
(FOX12, channel 13, 213MHz).  I'm using OTA DVB, and have been for a few
years now it has always worked.  About a week ago, I updated to SVN 14374
and noticed recordings we're being dropped, upon inspection I found that I
can no longer tune to FOX.  I tried using mythtv-setup to re-detect
(transport scan) channel 13 but it won't find it either.  I can use 'azap
-r' and mplayer and it plays the station perfectly.  I've tried using F7 in
the live tv to get the signal strength and it says 28% but I don't think
it's working right.  When I use dtvsignal I see FOX signal strength around
63%, I have other channels that have even less signal strength but don't
have issues recording with myth so I think it's some configuration issue.

I ran the backend with -v record and when it's attempting to tune to FOX I
see these messages:

2007-09-07 11:47:28.183 Could not find channel 12_1 in TVCT

Here is my channel database info:
