Hi. Im having some trouble with my dvd drive. I have tried several methods of burning, but I always have the same trouble. It will complete the burn process and say everything was successful, but then when I try to open it, its says the disk is empty. I have tried both DVD+R and DVD+RW. But this problem is only with DVD disks, cd's will burn fine. Also, it reads all other DVD's just fine. Any ideas on what I need to do to get this thing working again?
