Greets I may be incorrect but I think what auenf was looking for was: How do you disable buttons in a menu still compiled into a vob? ie. ripped from a movie. Say you strip out some of the bonus material, such as a behind the scenes featurette. Is there some way to disable the behind the scenes button (so when people click it, it won't crash the player) using ifoedit, vobedit or whichever without having to decompile the entire menu and rebuild it in an authoring program? I think that's what he was asking, and I'd sure like to know the answer myself :)
