Ok heres the deal. I have ,before thursday jan 27, Allways been able to make a back up of My allready decrypted and shrunk back-up. A friend came over asked for a copy of Alien vs Preditor. I copied it and when it was done it had a blank spot on the disc where nothing was writen. I thought it was My new DL DVD Burner. Took it back and the new one did the same thing. I originally had to use VobBlanker to rip AvsP. But when I use it on My back up. The Movie VOB says its skip within the list of Vob Blanker. Tried and couldnt get that to work. So went with DVD Decrypter and Nero same thing happend. Used ANyDVD/CloneDVD and same thing happend. My original back up plays fine. But nothing will copy it. And now for some reason all My old dvd back ups do the same thing. I got curious and tried to back some of them up and same thing happend. Its not My dvd burner as it is brand new. I have all the latest up to date software used. I even replaced My motherboard. Thjinking something was wrong there. If anyone can please give me and idea as to why this is happening. It would be greatly aprecieated. P.S. sorry for the novel post.
