Spritebox

I have a DVD drive and a DVD-R drive. I tried to burn a DVD for the first time the other day. I put the DVD in the DVD drive and the DVD-R in the DVD-R drive and opened Nero. I hit the start copying thing and my comp froze. I rebooted, and my computer no longer recognized my DVD drive. It wasn't in device manager or my computer. It won't even eject my DVD.

I know the DVD drive works fine. I've watched DVD's and listened to CD's on it many times before.

I really need some help here soon. The DVD I was trying to burn isn't mine and its proper owner is getting kind of impatient waiting for me to eject it.

Thanks in advance!
