ok so I got two videos from a friend of mine that he filmed and transfered. He did the burns on a standalone. When I try to rip them using DVD shrink I get on disc #1 an invalid file structure on and disc #2 just just a straight up error on the other. Tried just copying as a data disc and got disc #1 to copy, but disc 2 will not copy. Both disc play fine on computer and dvd player. Am I doing something wrong or just using the wrong software, Kirk
