yes and no, mpeg2/mpeg1 needs the blackboarders to maintain aspect ratio on a tv, if you remove the borders it gets stretched and mutated, another reason why it really shouldn't be used imo.
Anyway, if you remove borders on one side, you tend to need to add borders onto other sides to get it to keep its aspect ratio, on standalones anyway.
You can however crop with TMPGenc on one of its encoding steps.
I'm curious though as you didn't mention many details; if it is already encoded as an mpg, merely cropping won't make it any better, infact it makes it worse, its only when you need to re-encode the movie and compress it (ie DVD to avi), you waste bits encoding black borders when you don't need to (solid colour = very wastful for mpeg codecs).

Your doing it wrong then I would assume. MPEG4 is superior to MPEG2/MPEG1, it is a better quality at a smaller filesize, always. Your wasting bits, if its already 6mb, there's no point keeping the bitrate really high and everything, the damage, as it were has already been done.
A 6mb mpg should be ~3mb mpeg4, if your working with low bitrates, nero digital is ideal for this.
