I have another situation that's exibiting the same kind of problem.
I'm doing something a little more complicated, <whisper>pulling video
off my tivo</whisper> and then converting it to an mpeg4, but I still
think the mencoder step at the end of the process is where the delay comes
from.

First, I pull off the tystream and save it to a local file, convert it
to a normal mpeg using either tyc or vsplit+mplex, then use GOPchop to
keep only the parts I want.  At this point, I have a normal mpeg2 file
with _no_ A/V sync issues.

Then, if I convert it to an mpeg4 .avi with mencoder, the resulting file
has the audio slightly delayed.  It dosen't matter if I do a 1, 2 or
3-pass encoding (using the command lines from section 7.2 of the docs),
the sound is off.  Though the 2-pass file was closer to being correct,
it was still delayed.
