I've had three copies of Identity and all three copies skip at specific points in the movie. The first two skips occur early in the movie, while characters are running around in front of the motel. Thunder and lightning make these audio skips very obvious. The third, and most easy to locate, skip occurs during the orange grove sequence at the end of the movie when the character is hanging laundry (goto the last chapter and then backup a bit). I'm trying to figure out how it's possible to have this problem on three copies. I did get all three from Gamestop, but am sure that each disc was different. The idea of a studio dumping a batch of bad discs on a lower-tier retailer makes me a little mad (if that's what's going on here).
