There's a bad batch of the Hunger Games on bluray going around. Most of the bad disks come from Best Buy, but not all of them (mine came from Amazon). The problem is that the movie plays fine for about an hour, and at the countdown to the beginning of the games (when they're all standing on the pedestals), it pauses, then unpauses, then stops randomly. Some people report that disabling BD Live will fix it, but it didn't for me. I'm getting a replacement from Amazon, and will report back if it's better with a new copy.
thxs for the heads up. I just picked up a copy yesterday from Best Buy and was going to watch on Monday, but I check it out tonight.
