I created a iDVD project from a movie I made in iMovie. After watching the movie I decided to changes somethings. I added a couple of bookmarks. I saved the iMovie and open the former iDVD project and the movie update, but not the bookmarks. I don't want to create a whole new iDVD project as I have much work with a slide show in old one.

Is there anyway to add the new bookmarks or to get iDVD to recognize new bookmarks in my revised iMovie?
