Just recently i have been unable to copy Dvd's and CD's. I updated AnyDVD yesterday and i got a message saying that no DVD drive could be found. In device manager it says that the drive is working correctly, i can play CD/DVD with no problem, but can no longer burn either format. Burning CD is no longer possible on media player either, i guess that my DVD drive may be shot. Does anyone know how to test a DVD drive before i waste money on a replacement? Thanks!
