I had the same problem because mythtv gave the wrong time of my
recordings, as reported here
http://www.gossamer-threads.com/lists/mythtv/dev/86539. Maybe it's the
same reason for you. To check look at your framespergop setting by
running the command
ivtvctl -a | grep framespergop
If the framespergop value is reported to be 0, that't the problem. It
should be 12 or 15, depending on if you're using PAL/SECAM or NTSC.
It's a bug with the autodetection, so to automatically set the correct
framespergop value, you have to specify your tv standard when loading
the ivtv module:
ivtv_std =
