I had the same problem with this movie. All programs would get half way and have a cyclic redundancy error or something along those lines. THis is on the second disc I bought.
The first one I bought was cracked at the center where it is held by the case. Talk about lack of quality control.
I did think that it was interesting that this is the first disc I've seen that said "made in mexico" right on the clear center of the disc. Perhaps this is a trend that we can expect in the future? Cheap factories in mexico producing discs that can play but not be read by a computer?
