Note that this is for a PAL DVD - if you want NTSC you need to change
to -vf scale=720:480 and set the -ofps to "24/10001" or "30/10001"
(the first for movies, second for tv shows)

You could try dropping the -aspect option from the mencoder command
line and let mplayer calculate the aspect itself, it's normally pretty
good at that.
