Does the sync change over time or is it a constant delay?

Try playing the avi in vlc (or any other player where the sync problem
is evident) and use the "delay audio" option in that player, 'j' and
'k' in the case of vlc, to match up the audio with the video.

If it's a constant delay you can use the mencoder option -delay (or
-audio-delay, see man page for differences). It happened to me a few
times that the audio track was shorter than the video, resulting in
the delay when you encode.
