I just bought bad company for the PS3 from a local used games/video store and while playing it ran into read errors.. long story short, i eventually looked at the back and it looks like it's got a bunch of superficial scratches on it. I tried cleaning it off and it worked a little bit better but then started having problems again. I'm going to take it back, but my question is, I thought Blu Ray disks were unscratchable? Has anyone else had this problem? Am I wrong about them being indestructable?
