Well i master this one coarse on DVD. It first starts off with a disclaimer as the introductory video and then goes into the menu. The menu has 2 videos to choose from. I master 15 DVDs similar to this and 6 of them wouldn't work. Well, they wouldn't work in a standand DVD Player, but they will work in computer. When you put the good ones in, they go through the disclaimer, then to the menu and you can click and watch both videos. With the bad ones, as soon as you put the DVD in, it skips the disclaimer and goes directly to the menu screen. Then when i click on one of the videos, it freezes the DVD player up and will not respond. What would this issue be caused from? I do not want to re-dub hours of footage just to remaster. How could i fix this problem?
