Hey, I have an iMac i7 27", on which I have Windows 7 installed through Boot Camp. I'm currently encountering a rather annoying problem when on Windows: the DVD-drive isn't reading most discs; games in particular. It's working absolutely fine when I'm using Mac. I had this problem earlier when trying to put in Dragon Age II, but the reader just kept loading, and then it spat out the disc. The same thing happens now that I try to put in my (brand new) Battlefield 3 disc - it keeps reading until it eventually spits the disc out. I tried putting in another disc, a movie this time, and it didn't work. I put in another movie, only this time it did work. What is wrong? Why can't it read some discs? I've tried putting in the disc multiple times, restarting the computer and pushing in the disc while it's booting, but it keeps on spitting it out. What do I do?
