When I put in a disc it starts spinning then it stops and then it starts spinning again. It says the discs are unrecognized, the discs are clean with no scratches. It sometimes plays the game and it lets me play the game for 10 seconds but then it pops up that it can't read the disc so it brings me back to the Xbox home screen. It's an Xbox 360 Slim and I had it for three years.I tried other discs and it only fully reads one, it actually lets me play the game for hours, but it won't read the other discs. Please help i want to play Battlefield 4 !
