Hi, I just bought a Mitsubishi HDTV ready widescreen set and now looking for a dvd player. I was told that since we have HDTV we should go with a progressive scan dvd. While looking on the internet I noticed some say 480p while others say they are progressive yet do not mention this as one of the features. Are all progressive dvd players 480p or is this a feature I need to specifically look for on the dvd? Any advice would be greatly appreciated!
