I've used EM8 to create a DVD, consisting of a 1.5 hour video. The video is a single file. I created chapters, and grouped them into three submenus. When I burn the DVD and play it back, I can select the chapters via the icons, but the video doesn't play at the point that it was bookmarked. The icon, consisting of a frame of the video at the point of the chapter mark looks correct on the menu, but when the video plays from that location it starts from some other point. Does this feature really work? If so, is there something I need to review to get the chapters aligned correctly?
