I received a PlayStation 3 for Christmas, the Uncharted 2, Batman Arkham Asylum, and Infamous package.  I just got to play Uncharted 2 the past week or two, but for whatever reason the game is freezing upon load up. Upon entering the disc, it verifies and enters the screen with the dagger loading sign on the bottom right. It remains there for minutes, perhaps hours. There are no visible scratches or smudges. How should I go from here?

I just entered Bioshock 2 in to the tray and it properly loaded, but now is continuously freezing. Perhaps it may be just a problem with my system?

Call Sony and Google your issue to see if this is a common problem. 

Yes, it must be your PS3.

Its most likely your PS3 that's the problem.
