I have problems playing this disc on my Xbox, PS2 and my Powerbook (My stand-alone player broke, and I'm a poor college student so buying a new one isn't high on the priority list). It freezes at Chapter 13 on the first disc. Everything disc two seems to be fine. I have heard some discs don't play well on certain players, like an Xbox or PS2. I need to find out if my disc is faulty so I can send it back to Amazon while they still have these in stock. So if you have this disc and an Xbox, can you please test this for me? Thanks.
