You may want to consider that your hard drive could be failing.
Try running the game with the hard drive removed. If it plays then that means your hard drive is failing.
This may sound strange to you but trust me I know.
You may be able to find better help by googling "disk wont read xbox 360" and go to the Xbox dot com link that comes up.
