DVD Video Upscaling – Important Facts
It maybe somewhat confusing to read about a upscaling DVD player that outputs at a HD resolution and then read that a next gen player also has that same output resolution capabilities. About.com has all the information you need to know regarding the difference between the two players. Upscaling DVDs is where HTPCs got their roots. I remember several years ago fooling around in powerstrip and seeing if my GF2MX video card could handle upscaling.
From the article:
However, upscaling, as it is currently implemented, cannot convert standard DVD
images into true high-definition images. In fact, although upscaling works well
with fixed pixel displays, such as Plasma and LCD televisions, results are not
always consistent on CRT-based high definition televisions.
