Not sure if this is the right place for this issue but a friend's DELL Dimension 8200 desktop system with XP PRO suddenly began having problems playing DVD movies. When she tries to use Windows Media Player, she gets an error message saying that "Windows Media Player has encountered a problem and has to close" . When she uses POWER DVD, the dvd movie plays the audio but the image is all "pixelly" for lack of another term. I switched out the actual DVD drive and we are having the same problem with the replacement drive. She has uninstalled and reinstalled both Windows Media Player and PowerDVD. Also, when you put the DVD disk in the drive, normally you could hear it "spin up" but now the lights on the drive blink but nothing else happens. Thanks for any suggestions and help.
