I have a Lite-On 48161h combo DVD/CD drive and for the last year it worked fine but now it only wants to play CDs. I have tried DVDs that I?ve burned myself, actual DVD movies and a data DVD, all with the same result ? the drive just spins with the light flashing at the same regular rate, then it stops with the result that it reckons the drive is empty. I have several other DVD drives one in the same computer and all read the same discs fine. Oh, and I have the same drive in another system which still works fine. I think the drive is defective and out of warranty but am willing to try suggestions.
