I use dvd shrink, could just be a faulty dvd writer. Or some software is in conflict with shrink but I have lots of software on my pc and have no problems. If you copied a dvd and its skippy could be you were using your comp while it was doing it? maybe turning off some of your processes might help. Try other burning software to see if it works like nero put some data on a dvd and see if it copys. If nothing else works then id presume its your dvd writer packing up.
