Trying to help my dad figure out what is wrong with his laptop (in other words, what he goofed up!! ) His Gateway laptop has a dvd -r/rw drive. Laptop is maybe 1 - 1.5 years old. The laptop will not show store bought DVD movies. You can feel the drive spinning, but nothing shows on screen. Have tried a couple of different dvd viewing programs (Cyberlink, WMP and one other one) but to no avail. Windows Explorer does not show any files on any of the dvd’s, looks like they are empty. Same DVD's play ok on my PC and on standalone DVD players. DVD drive will play audio cd’s. Problem seemed to start after re-install of Windows XP (or so I am told). DECCHECK shows the cyberlink decoder is the preferred decoder. Have not tied to delete the IDE/Drives in device manager since it will play audio cd's. Suggestions?
