Just hooked this up and, all I can say is WOW. It does a great job with SD. I hooked up a PS3 and popped in a blu-ray movie (King Arthur), and the picture was bad, not very bad, but a little grainy. Something was definitely not right. I'm going to try another blu-ray movie tomorrow and see if it was just the King Arther film. I put in a regular DVD in my upscaling (to 1080i) panasonic DVD player, and I was amazed. at about 10 feet away, it was like watching 1080P HD. Very clear picture. I don't think you would even need an HD DVD or Blu-Ray player, the picture is that good. I have to say after I saw the picture clarity on the sammy, I moved the panasonic dvd player back to my theater to see if the picture would be that clear, the samsung definitely beats my projector in SD movie quality (For comparison, in the theater is a JVC DLA-RS1 1080P projecting onto a 110" screen, seating distance at about 14 ft). By the way, I'm very meticulous about watching movies/TV. The picture and sound have to be perfect, and I would say that the bowing is not a deal breaker for me. Also the bowing only happens on the bottom, not the top on my TV. I'll let you guy's know about the Blu-ray movie tomorrow. Also if anyone else can test out a blu-ray or HD-DVD movie, please let me know the results. Thanks.
