I'm using DVD Studio Pro and I'm trying to make a menu for the first time. I've learned how to link the buttons to different chapter markers, however I'm having difficulty adding the video above the buttons. I have the 15 minute video in one sequence, with about 8 chapter markers. I guess what I'm asking is how do I separate, or edit, certain clips from my sequence in DVDSP to add above the buttons as a preview video?
