expand is accurate, the scaling method I wrote is not:
when played VCD are scaled to 384:288 because of the A/R, so
to make things perfect you should do so:

mplayer -vf scale=384:-2 dvd://
and take notice of the reported y value, then round it to the closest
multiple of 16 (say y'), then

mencoder dvd:// -vf scale=352:y',expand=352:288 ...
