I bought a dvd burner external, hp 1040. I use my roommate's dvd burning program which is just dvd shrink 3.2. The dvd decrypts fine and encodes fine but then when it burns it burns a couple % and stops and says error. Then if I do it again it works fine. So this wouldn't be a problem except my dvd's are not rewritable and therefore ruined. So it is costing me two dvd's for every one i burn. This has happened on the last 4out of 5 dvd's ive tried to burn. Any thoughts?
