I currently have the Zenith C27V36 HDTV with the Toshiba SD-3900(progressive scan) dvd player hooked up with component cables. I watch dvds in 480p mode. Since I have an DVI input on my tv, would I benifit in a dvd player with DVI out? Also would I notice much of a difference with 1080i over 480p on a 27" screen? I'm interested in getting the Samsung HD931 dvd player, if there wold be a noticable difference in picture quality.
