Hi, storm. I too have a question on that. What does that setting do? Here is basically what I want to know. I have that checked and have made an iso of a dvd9 movie. As a test, I first tried Nero with verbatim discs. Movies don't play well in my dvd player. Next, I tried IMGBurn. Movies play fine. IMGBurn asks me to pick the layer spot. Is DVDFab doing this for me? Also, if I don't have success with Nero 7, is it likely I wouldn't if I choose Nero 7 as my burner in DVDFab? Right now it's set to VSO.
P.S. I am waiting on some more DL discs, that's why I can't test any of this right now.
