I just bought Fallout: New Vegas and i was able to play for 15min before it crashes and say disc unreadable. I restarted my xbox and now it just wont start anymore. I went to the store and changed 3 copies of it but they all do the same. On the forum i read about "clearing the caches" wich i did and it works. But every 5-10 min or so it say disc unreadable again. To play again i have to clear the caches again. So it has been going for a while now i got 2 hours of game play but each 5-10min i have to save before it crashes. Anyone know a way to fix this?

I think this is a problem with your Xbox disc drive you could have 1 of 3 disc drives (Samsung, Hitachi, and one other). Some cause serious problems, and right now it looks like yours is one of them. Sorry guy

But why this game only? Deadrising 2, Halo Reach, CoD MW 2, Fallout 3, etc.. They all work.
