Error Message when trying to complete my IDVD Project?

Question

I'm getting an error when I try to either burn or ave my project to a disk imahe or TS_Video folder. The error message says:
++There were errors during the project validation that have to be fixed before burning the project.++
How do I go about debugging the problem. I have created many IDVD projects but have never had this issue.
I'm using IDVD 08 and using an 08 template.
Thanks for any help,
Steve.

+I am wondering why you have stuck with a G4 and OSX 10.4.11?+
I can answer both questions in one answer: Flawless performance and compatibility with my applications. I didn't see much value in Leopard for my computer (G4). Mac Pros get faster and cheaper every year.
+Is there a way to make the submenus different from the first menu?+
Maybe in the themes with little triangles that expose other menus? Or maybe when you're on the submenu, just switch to another menu. I've never done that since I like to carry the theme throughout.
I'm not sure about the motion menu issue... I had that in Pass Through one time and had to stop all motion and remove music. It was a pretty complex project. Here are my notes on that project:
*Ireland 2006*
iDVD 6 Pass Through widescreen theme
696 images that are 2816x1584 pixels shot with Canon SD700 IS
15 640x480 movies from same digital camera transcoded to H.264 with QuickTime Pro.
Part 1 and Part 2 submenu buttons on main menu. All submenus are the Chapters option for this theme.
Part 1 leads to a submenu. That submenu has additional submenus and sub-submenus. Part 1 leads to 12 total submenus. These menus contain images and movies.
Part 2 leads to a submenu. That submenu has 5 submenus with only images.
I had to "remove" animation on all the sub-submenus and not include any music to get everything on a single-layer DVD-R. The Menu info was WAY over the 7:30; something like 14:00 after these adjustments. About 20 slideshows with music. Additional short slideshows with no music.
