I am atemping my first DVD authoring on LE with more than 12 chapters. This project has 42. I understand that there can only be 39 buttons on a menu. I created 2 menus, one with 30 buttons and a next button and one with 12 buttons and a previous button. How do I link them to the timeline and each other? How are pages created? What is difference between a master menu with chapter menus and pages? And what are the different uses? I have two training videos and two books and none address these question very well.
