Okay here is what I know. After upgradeing to 15784 from 15578 when I tune to a channel I get a error in the backend and cpu goes to 100+%.

Snippet backend.log:

2008-02-06 15:38:57.952 TVRec(3): Changing from None to WatchingLiveTV

2008-02-06 15:39:12.940 TVRec(3): Changing from WatchingLiveTV to None

I have removed all inputs and added them back (sometimes this fix the problem). I have removed, purged, packages then reinstalled. I havent started from a new database. The device is a ASUS TVFM 7135 v4l analog capture card it has work flawlessy up until this last upgrade. I also have a pcHDTV 5500 card that uses dvb it doesnt have this issue, it seems to be with the v4l device & mythtv.

NOTE: This is my first bug report for mythtv hope I didnt leave anything out.

Some more information that might be useful is that I am using SVN trunk build. Also the v4l tuner works I can watch and record shows at the expense of all the cpu power.

I dumped the database to check if that corrected the issue and it did. While i was configuring mythtv-frontend I changed the recording profiles from RTjpeg to MPEG4 and the issue came back, 100% cpu on the backend. So apparently the issue is there.
