Loaded resaved iDVD6 proj from orig iDVD5 causes hang.

Question

Up front - I've already applied the recent updates to the iLife suite. In another thread I got worked out how to get iDVD to open and actually import an iDVD5 project. However, now when I save this project and try to reopen it, iDVD6 hangs. If I kill the .plist and the /user/library/application support/idvd/themes folder, clear trash and reboot, I can get the project to load. However, this is a tedious process to follow each time.
The projects (there are two) are both multi-chapter picture slide shows w/ music applied. When I upgrade to iLife'06, the iPhoto app did some moving of files and subsequent changes have moved the images as well. However, when running the import it asked to search for them, and found them. Now the new project is saved and will only open if started from a fresh .plist. If I start a fresh .plist, create a blank project, save it, and quit/restart iDVD, it works fine.
Any ideas? My wife put a lot of work into those and I'm trying to save the work of having to recreate all the slideshows and such. Thanks,
Mike

Is there a reason a new update to QT would not recognize the motion menus in iDVD?
I have another thread going:

and am wondering if this is causing my problem also. I just tried to burn a non motion menu project to a disc image and it worked fine. I can kind of navigate my current one, but it hangs when I go to render the menus or even turn on the motion previewer.
