It appears to me to be another faulty cd/dvd drive just as my original Xbox had. Though they fixed those by using the Samsung drives instead of the Thompsons. My 360 appears to be having the same problem, along with other problems. Its prone to locking up, overheating, and just now claims it cannot read a brand new disc which has not one speckle of dust on it! Microsoft really needs to fully test this crap before they send it on the market. Im tired of them using crappy hardware. Granted the graphics are great, but the hardware is far from reliable.
