I was wondering if anyone else has had the Amped disk be rejected by their xbox? I have had it happen twice. The first time the game froze during play and finally the message screen about an incompatible disk came up. I ejected and re-inserted the disk an all was well. The next time it happened was as soon as I put the disk in. Again, I took the disk out and put it back in and it worked. Seems freaky to me, either defective Amped disk or my xbox is glitchin' up on me. I have also experienced some other lower-level glitches if anyone is interested I can post them.
