I am having the same issue and discovered that you have to select the proper disc for it, you need a bland DVD-VR or DVD+VR. When you go to "Produce Movie Disc" it comes up with a screen saying Select Your Disc. Under the 2nd one, be sure to select which of the discs you are using.
Problem is, I can't find these discs (VR) anywhere. I've been to a bunch of stores but no one's even heard of them. Do you or anyone else know where I may be able to find them?
