n/a, but mplayer works fine for me.

I use:

mencoder -dvd 1 
  -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=$RATE \
  -vop crop=$CROP,scale -zoom -xy 640 \
  -oac mp3lame -lameopts abr:br=128 \
  -o file.avi

I calculate the crop value with:

mencoder -aspect 16:9 -dvd 1 \
  -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=$RATE \
  -vop cropdetect,scale -zoom -xy 640 \
  -oac mp3lame -lameopts abr:br=128:vol=9 -o /dev/null
