There are more places that themes can be stored as in
The iDVD application it self.
Goto Application folder
select the iDVD icon - BUT keep ctrl-key down
now a menu will unfold
select - Show Content of Package
Second choice (under Open) - Visa paketets innehåll
and here You find Contents
and in this Resources
and here I find my iDVD themes

Did you look in the right library folder?
Or you can use the shareware app, Find Any File, to search for ".theme". FAF can search areas that Spotlight can't like packages, invisible folders and system folders.
Check in your Home/Library/Application Support folder. Earlier versions stored them there.
Did you upgrade to Mt. Lion since the last time you've tried iDVD? If you did that may have removed them. You know the User/Library folder is not invisible.
NOTE: In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
If there are no themes anywhere on your hard drive you'll have to reinstall iDVD from the disk it came on originally. If it was included with your Mac use the disks that came with the Mac. It'll be like one of these:
I slowly upgraded from leopard over time and just tried the snow leopard install disc and it did not work. Lion does not have an install disc so you can't go back to do a custom install.
The menu in iDVd I can't get to.
The program warning comes right after I try to make a new project.
Apple really needs to address problems like this where OS programs have problems and there is no way to reinstall them since it came from a download which is fleeting.
