In the past couple of weeks my PS3 would hang up when watching movies. It would hang, and then start playing on its own. It only happened two or three times. Then this week end it got so bad it would say error reading disk, or not even see the disk at all. Got tired of messing with it and ran out and bought a 120 Gig Slim. Has any one ever changed out the Blue ray drive on thier PS3?
