Hi, I'm an absolute newbie when it comes to all this HD and resolution stuff, so have a simple question. I've read that some DVD players you can 'upscale' DVD's with, to make them look better. Can you do this on the Xbox 360? And I know it has a progressive scan DVD player, would all DVD's play in this mode, and how does the picture compared to an 'upscaled' one? Basically I don't know whether I should use the 360 for DVD playing, or to buy another cheap one which upscales. And what exactly does upscaling do, won't it distort the picture?
