guys, there's something i don't understand.

currently i'm having a panasonic dvd player and a philips hd lcdtv. the highest video resolution the dvd player can go is 480p.

a dvd disc only can go up till 480p max, no? on the other hand, i'm thinkin does a hdmi dvd player that does 720 or 1080p can play or upscale the dvd at 720 or 1080p?

i'm getting confused. how bout upscaling that you guys are talkin about? does it really improve the quality? if that's it, how about mp3 and etc? a low bitrate sucky quality mp3 played is still poor even it's encoded at a a higher bitrate.
