Because I didn't get a response from you, I thought maybe you didn't want to
use mpeg-2. Here are a couple of conversions to other formats that seem to
remedy unmatched video and sound.

mpeg4 AVI output

mencoder -ovc lavc -oac copy -vf scale=720:480 -lavcopts
vcodec=mpeg4:vbitrate=3600:v4mv:mbd=2:trell:cmp=3:subcmp=3:autoaspect -mc
0.1 -ofps 25 -delay -0.3 -o /Users/me/Downloads/hdpreviewfast.avi
/Users/me/Downloads/hdpreview.m2t

h.264 mp4 with faac audio

mencoder -oac faac -faacopts mpeg=4:object=2:br=160:raw -channels 2 -srate
48000 -vf scale=720:480  -ovc x264 -x264encopts
