This is HORSESHIT. We all have the same issue with no solution. They had the nerve to post this http://support.activision.com/articles/en_US/FAQ/Game-Will-Not-LoadDisplays-a-Da ta-Read-ErrorFreezes-on-PlayStation-3 Like the problem is someone elses and not their own.
I took my copy back and exchanged it. So far no problems. The guy said at gamestop that its either the disc or the ps3, and since it did the same thing on both of my systems, he said more than likely it was the disc. See if you can exchange it and hopefully that's the problem. I know its frustrating because mine froze up 7 times last night and twice today before I called and took it back. Like I said though, no problems with the new disc.
