I watched 300 blu-ray on a 50" HDTV Pioneer Plamsa, with 7 speaker surround sound, and I really enjoyed it. I though it looked good, although not quite as good other BDs I have watched, like Casino Royale, but I supose the one to test HD with is the Simpsons Movie, or better Spiderman 3
I am not sure whether my TV is 1080p compatible. While it does say the maximum output is 1080p, when I am in the XMB is uses 1080i (actually 1125i), although I think that it did change upto 1125p for the movie, but I'm not sure
