I had this problem before, And believe me. I was pretty pissed. What good is a disc that you rent or buy that you cant even play because of some stupid copyright protection. I dont care if it was a screw up, They shouldnt bother with it in the first place IMO.

Its like when we rented some movies from blockbuster and the dude didnt take out their little security device from the case. I just cut the thing open. If i really wanted to steal the disc I would just bring some magnets and take it off in the store myself
