I am having difficulty locking the live video start frame for each chapter button (NOT background image) in iDVD. I create the chapters in iMovie, send to iDVD, set theme preference (i.e. Theater, Book, Projector, etc), then create the Scene Selection preference theme. IDVD automatically imports the live video image from the iMovie created chapters. So far so good, however, when I click once on one of the buttons (either with Motion on or off) I get the Movie checkbox and the slider bar. As I understand from reading the iDVD help file, I should be able to move the slider to a point within that video section (or anywhere in the full video for that matter) and the live video should be viewable from that point when burned to disk. It does not stick! I have tried setting with Motion on and off, saving project before moving to next step, setting with Movie box selected and unselected, etc, but to no avail I have yet (in MANY efforts) been able to get the selection to work as stated in the iDVD help file. Anyone else encountered this? Any suggestions? I am running 10.2.8 on an iMac 1Gh, QuickTime 6.4, iDVD 3.0.1, and iMovie 3.0.3. Thanks all.
