I don't think so. The video timestamps are pretty regular, every 480ms
(one per 12 frames). MPEG and AC-3 audio timestamps are in 144ms and
160ms intervals, with only small deviations (+/- 2 now and then) in the
AC-3 track.

I can't reproduce that with the 2min snippet I downloaded :(
I get at most one message.

And it's in the AC-3 audio track this time. So far dvbcut only detects
and corrects PTS errors in the *video* stream. It doesn't even look at
audio PTS when indexing.

Maybe the problem is somewhere else in the stream. Or there are lots of
small errors that accumulate. Do the sync errors go away after a cut
point? Or do they get worse and worse until the end of the movie?

Did you try to play the DVD on your computer, e.g. with xine? Or did you
just play the "vampsed" file?
