   Hi,

I had a similar problem with A/V desynchronization. Playing the original
stream using mplayer the A/V was synchronized. After re-encoding using
mencoder the A/V streams get desynchronized. I did a small work-around
for this:

mknod stream.dump p
mencoder -oac ... -ovc ... -o output.mpeg < stream.dump &
mplayer -dumpstream video.avi

    ... and both streams in the output.mpeg file were synchronized again.

Hope it helps.
