This has happened to me before, and I forgot how to fix it - I had some problems with InCD conflicting with U3 flash drive. I see my DVD drive as a D: Drive but no application recognizes it, and if I double-click it open it always shows empty no matter what media is inside it. Auotoplay does not recognize it or launch a DVD title either. I've tried firmware update, uninstalling, nothing seems to work. As I said I fixed this one other time but can't remember what I did. Anyone have any thoughts? Thanks.
