scratch Master 360

My 360 has decided it does not like discs. It demonstrates this by scratching the hell out of them. It chewed through COD4 and Mass Effect. I was able to buff COD4 back to life, but it was too late for Mass Effect. Fortunately it was still covered under the 30 day warranty at Futureshop and I was able to do a disc exchange. So now I am out a 360 until it gets repaired. Well I can play all the XBLA games I want or download some Xbox Classics, but I am not putting anything in the DVD tray. This will be 360 number two since 2005. I guess I should consider myself lucky this one lasted as long as it did.
