I own this player- using it on a 50" Panny-I bought both the player and TV from costco-it works pretty good-I do believe there may be some macroblocking issues using HDMI (which is the way it upconverts) on some darker scenes-but this may be specific to my set-but overall it works pretty good-some movies like return of the sith look great. I do not own HD DVD (although I am tempted) so I cannot compare to that. AVS had many pages on this player. Tim
