I just found this same command for VLC last night.  I don't know if
this will help with your particular movies, but this is the mencoder
script I used to convert to xvid.  I preserved AC3 sound since I used
SPDIF with a audio receiver...  (You can use "mplayer -vf cropdetect"
to detect the proper crop settings if you want to remove black borders
on widescreen movies.  If you search you can find a cropdetect.sh
script online that will do this quickly for you.)

# video track (pass: 1)
nice -n 3 mencoder -sws 2 -oac copy -ovc xvid \
 -xvidencopts pass=1 \
 -vf crop=720:352:0:64,scale=704:304  test.ps -o /dev/null

# video track (pass: 2, bitrate: 800)
nice -n 3 mencoder -sws 2 -oac copy -ovc xvid \
 -xvidencopts pass=2:bitrate=800 \
 -vf crop=720:352:0:64,scale=704:304  test.ps -o "movie.avi"

I haven't watched the whole movie yet (this was Snakes On A Plane last
night), but skipping around to test showed no audio sync issues.
