I have a DVD-Rom and a DVD-RW on my computer. The DVD-RW drive reads as a CD Player when there is a disc in. When the disc is out the icon reads DVD-R drive, but the computer is still reading it as a CD player. So it looks like I have 2 CD players on my computer. And of course when I try to burn something, it doesn't. I get a message saying something like not a recordable disk. Help!
