I think you're confusing tracks with chapters. each track can have a different number of chapters. drag and drop your source, then go to cut/edit and make chapters, then add a new track, drop your source, go to cut/edit and make chapters, etc. then when it comes to making a menu, choose top and track, 4 thumbnails for your top menu page, and however many thumbnails you want per track page.
