There seems to be a misconception here that you can only add chapters to one movie when importing to iDVD. Au contraire. Finish your editing, add your chapters and save your projects. Then go to the top level directory in each of your project folders. You'll find a quicktime reference movie there named the same as your project, e.g. myproject.mov. Just drag these over to iDVD and drop 'em in. All the chapters come with the movie in a separate chapters track. You can prove this to yourself by opening any of the project reference movies in QuickTime (you don't need pro). The chapter markers appear as a pop-up menu at the lower-right of the movie track. If you do have QTPro, do Cmd-J and look at the left pull-down menu. You'll see the Chapters Track as a separate track. - Erica
