i have the ps3 with blueray and i have blueray movies at 1080p .But yesterday i watched a DVD of my sons this also was in 1080p and well it looked amazing so if a DVD is 1080p and blue ray 1080p is there a lot of difference as DVDs are now cheaper
dvds are not 1080p. bluray players will upconvert a dvd to 1080p resolution so that it looks better on an HDTV. however, they are still only dvd quality as the bluray player cannot create the extra detail that a bluray movie has
