Sony doesn't have to support quicktime, WM9, MPEG4, MPEG2, AAC, etc. All they have to support is their standard (likely an MPEG4 type). cheaper hardware.[/quote
? The CPU in the PSP is more than capable of decoding those filetypes. And Sony don't have a vested interest in a particular video codec, unlike audio. Whether it supports any/all of those is another matter.
with one of the other media players, most of them include programs that will shrink your DVDs down to be played on them. So you buy a DVD and can play it multiple places..
They shrink, but only if you don't have CSS on the discs. So commerical DVDs cannot be shrunk. Sure, you can download additional software, but the manufacturers can't supply that as it breaks the protection.
I expect Sony to have something similar to load onto Memory sticks. Designed for your 'home movies' naturally, but run your DVD through DVD decrypter first and you are away.
