I don't know that I've heard of anyone with sync problems with
ProjectX. Have you made sure the original doesn't have troubles before
demuxing?
Also, you may try the non-demux option of ProjectX. I think they
call it "M2P" for MPEG2 Program Stream. Is it an ivtv stream? Just
making sure it's not DVB.

I dislike Java almost as much as I despise perl. To be fair,
though, I haven't had any stability issues with ProjectX. I installed the
J2RE straight from Sun, though... no rpms or anything.

That's usually what causes it. Tape transfers seem particularly
bad, since VHS/8MM are generally pretty awful about TBC... TVs are pretty
forgiving.
