I have a Dell system and have been using shrink and decrypter to burn movies for about 6 months now without a problem. Now, all of a sudden, my computer will not recognize the movies on dvd. When I put the dvd in, a few noises and then nothing. Every now and then, it will recognize and play. None of my programs work--windows media player, dell entertainment program, real player, even shrink comes up with 'no disc' when I try to open it for backup. Stanger though is that everytime I put in one of my burned copies the computer recognizes those disks every time. And I am using some CHEAP media for those. I have already upgraded the DVD Decoder and no change. Hardware problem or is there something out there I can just download?
