question 1, I have tried this twice. When I play it in a standalone player, it only plays the extras. Will not play movie. I used DVD Fab decryter and vob blanker and ran it shrink. Tried 1 in full disk and second in was main movie, even the main movie will play the extras, but not the movie. question 2, what is the best way to clean the lens. I have a brush cleaner, but don't feel it does the job well. THX for any advice.
