I just got the game on Christmas, and I've had a few problems. One problem I've had is that the game freezes sometimes at the Press Start screen. Also, while playing the game I have had some freeze-ups and slow downs (while fighting, moving, talking, or in the pause menu). Also, I have started to notice my Xbox making odd sounds...like a whirring sound of some sort. My Xbox happens to be one of the first models released, so perhaps it's beginning to get old. I also finally picked up an Xbox DVD Remote, and I don't know if that might drag the system down a bit. And no, my Xbox is not a modded one. One last thing, I also rented the game before recieving it, and the rental copy worked just fine. I'm not sure if I should exchange it, or if there is a possible solution to sort of...give the system a boost. Any hints or comments would be appreciated.
