I plan on getting a Sony PS3 very soon. I'm watching Spiderman 3 on Starz HD, and I'm not exactly impressed by the quality. It looks good in their HD, but it still is blocky and even the video gets choppy at fast speeds. I know that BD stuff is best experienced at 1080p, but I simply don't have that. Can I expect better than cable quality on my BD stuff at resolutions lower than 1080p?
