Let's say I've a got a project that is a little over an hour. For arguements sake, call it 1:15. Lets also say I've got 21 chapters with a total of 12 minutes of motion menues. I'm using iMovie4 to compose the project.

Now lets say I use iDVD4 to burn. When it (iDVD4) first comes up, it automatically creates a series of menues with the 21 chapters.

Now, if I drag the movie to the Autoplay-Well, am I essentially encoding and burning the movie twice? Will I end up encoding 2:30 minutes of movie footage and 12 minutes of motion menus?
