Yeah, I guess you might want to uninstall DVD Studio and try again. Try these instructions:

Maybe imovie does provide templates. Did you remove it just to free up space? I'd say if you really want to free up space, you might look at removing the livetype stuff. It's a fairly cheesy application.

Yes, LiveType could be removed, but "cheesy" isn't a very objective assessment. There have been recent threads by PC users on this and other sites about LiveType, asking if there's anything like it available for them. I agree that some of the animated fonts might have "limited application" (a euphemism for "useless") in weddings, but the application is very powerful and flexible. Maybe locating the animated font library (which is large) and maybe the Soundtrack Pro loop libraries (also large) on an external drive would be a better choice.
