Hi Torbj�rn,
Thanks for the reply, I resolved the issue. Short answer: there's no bug
in your filters, and the bug was in my patch.
Long answer: it was caused by my first attempt at a seek synchronization
fix for the MPEG4 files the Plextor hardware generates. I was dropping
frames up to the first I-frame which mostly solved my seek problem. But
that fix is no longer necessary now that I am generating NUV sync frames
synchronized with the I-frame in the MPEG4 data coming from the hardware.
Cheers
Jack

I haven't followed this thread very closely, but is audio always out of sync
or only after you have seeked forward or back?
And it's not safe to asume that all keyframes is keframedist frames apart,
remeber the file can have been transcoded and cut.
Getting the audio and video timestamps right is a bit complicated, for
example the filters have to take into account that timestamps can have some
wierd values especialy at the begining of the file and just because the
seektable says there is a keyframe at a specific position doesn't mean that
is always the case (old bug in mythtv, fixed long ago)
