Lately I have been having problems when I am trying to back up my DVD's. I am currently using a Lite-On 16X dvd player in my D:/ and my MadDog DVD burning in my E:/. My DVD player is about 3 years old, came with computer. I am using DVD Shrink and when it is the first stage of encoding the movie it tells me I have a "Cylintrical Disc Error: Dvd Shrink cannot read the DVD". If this a problem with my DVD drive or DVD Shrink? It seems to only do it on certain movies but not all. I have cleaned the disks and some are brand new so there are no scratches on them at all but I still get the error. Any help would be appreciated.
