I bought an internal Philips 8631 dvdrw for my computer in January 2006. It worked beautifully for three and a half months and then ceased to recognize dvds. (same brands, same package of dvds) It became a dvdrom only overnight. I spent hours with Dell tech support, nice people, tried many things. They sent me a replacement - a Philips 8801. I installed that one and it never recognized a dvd at all, played a dvd movie fine but if I put a blank dvd (again, same brand, package) the icon on My Computer screen for that drive changed from "dvdrw on drive D:" to "cdrom on drive D:' No kidding, freaky to see but happened every time. After 3 hours with a dell tech again, I took the replacement out and put a plain old cdrom drive in and it works fine. This tells me it isn't the cables or basic computer. Has to be the Philips drive. Can anyone help? I have pretty good eomputer skills, but I am stumped. Dell is no help. Any assistance is appreciated.
