Not being a techie, it is possible by the way that DVDShrink analyzes and encodes a disc, for a drive to suffer premature failure? I have been using my DVD-ROM drive for this and a Pioneer A06 for burning. Yesterday the DVD-ROM (Samsung that Dell supplied with computer)started acting up. It would read a DVD (burned or original) but during the playing process would speed up/slow down with distorted sound. I have checked that it is not a software fault by running the DVD in the burner and it plays normally. I have not changed any preferences/settings in the past two weeks since I started burning and it has worked fine until yesterday. I'll be calling Dell tonight to see if they can fathom it out. Any thoughts?
