I also have this problem - but not all the time. It seems to be specific
to particular movies or programs and can vary from channel to channel.
Other things I backup to DVD seem to be perfect all the way through.
My setup is DVB-T only (at the moment) and I'm in the UK, so that means
PAL and input format MPEG-TS. Now I suspect that what might be causing
(some of) the problem is frame rate. If the program is broadcast at
25.00 fps instead of 24.96 (or vice versa, the math is making my head
ache) and the splitting/combining that goes on within the mytharchive
scripts are assuming different things with regard to audio and/or video,
then that could about explain the kind of effects I'm seeing. In my
case, the audio always ends up in front of the video, the offset
gradually increasing with the length of the feature.
Other movies, presumably broadcast in a slightly different fashion,
don't seem to have these problems. We do know that different
broadcasters tend to handle things differently from time to time. There
was a recent thread on here about channel Five changing interlacing and
other things *within a movie* so nothing would surprise me.
Qusetion is, how can we improve mytharchive so that these variations are
detected and handled? Does mytharchive assume that the fps, interlacing,
etc it detects at the start of a recording are constant all the way through?
