Hi all, I just wanted to share a little info to you all. First of all I have around 20 to 30 original DVD's that where damaged in the desert (Iraq) I mean these things look really bad. I have been trying to back these up to no end. I have tried every setting in every proggy out there. I have tried every way possible to clean these puppy's and still no luck. :-( Well now the good news. If you plan on backing up a lot of DVD's I would recommend spending the $50 for the electric SKIPDr. I am telling you now this thing works I couldnt believe how good it works. What it actually does atleast from what I can tell is it actually resurfaces the disk. I have been able to back up 21 out of 21 of my DVD's that I took to the desert with out one hickup yet after running them threw my new investment SkipDr. This was the best $50 I ever spent!! I bought the other supose to be repair/cleaners for $20 and they never worked, and I didnt really feel like spending $50 for this, but I tell you now I am happy I did Anyway I just thought I would let you all know if you can't get a disk to rip to your hard drive after trying everything under the moon then you might want to invest in Motorized SkipDr.
