You’d def need a HDTV…720p, 1080i or the grand daddy 1080p. I truly dislike Sony for a number of reasons. One of them being that they decided to develop Blu-Ray in the hopes it would be the successor to DVD. Sony has failed so many times in its attempt to push a new form of media…Anyway i’m getting off the subject. As far as specs go, Blu_Ray is slightly better than HD DVD. My guess is that, a normal human being wouldn’t be able to tell the difference between HD DVD and Blu-Ray if displayed on identical TV’s.
