Okay, this is weird. I have a DVD Burner on my computer, (NEC 2100AD) and it will burn CD-R media just fine. When I try to burn a DVD, I get a message saying there is no disk in the drive. I've tried several different brands of DVD-R media (Sony,Maxell,TDK,etc...) but they all give me the same message.
Why doesn't my DVD burner like DVD-R's? It seems to like CD-R just fine!
