Hey, have any of you guys experienced the "dirty disc" error during gameplay? I've had it freeze w/ that error, and also just freeze totally w/ no error. It has happened twice during cut scenes during gameplay and twice when I have hit the "start" button and in the instant replay mode and once on a snapshot. Just checking to see if anyone on tidefans has had this problem. I've noticed that the subject has been popping up on several gamer boards...thx
