First let me say that this is the legit retail version. I don't pirate PC games. I have a 20X SATA LiteON DVDRW and it absolutely can't handle the Crysis DVD. It spins up and then I hear kachunk, vroom, kachunk, vroom... I've been reinstalling software all weekend because I just reformatted, and the drive has no problems on any other disc, including other games. I had to put the disc in another PC's NEC 16X PATA DVDRW, share the drive over the network, and install that way. Does anyone else have this problem? At this point I might have to image the disc on the other PC, copy the image, then mount it in daemon tools. Or just go get a crack.
