Re: Problem With IDVD Launching

Apple posted a solution to this problem. It has to do with old themes and offers a fairly easy fix.

iDVD '08: The application may unexpectedly quit when opened for the first time
Issue

iDVD '08 may unexpectedly quit when opened for the first time, after installation.

Affected products:

iDVD '08
Solution

Have your iLife '08 installation disc nearby before performing the following steps.

Erase the following folders from your hard drive:
/Library/Application Support/iDVD/Themes/iDVD 1
/Library/Application Support/iDVD/Themes/iDVD 2
/Library/Application Support/iDVD/Themes/iDVD 3
/Library/Application Support/iDVD/Themes/iDVD 4

Erase the following folder from your home directory:
~/Library/Application Support/iDVD/Installed Themes
Note: The tilde (~) represents your home directory.

Reopen iDVD '08.
To Reinstall Themes 1-4:

Open iDVD '08 and open a project.
Click Themes.
From the Themes drop-down menu, choose Old Themes.
Select any of the faded-out theme thumbnails.
Follow the on-screen instructions to install all of the themes originally erased via Software Update or the iLife '08 installation process.

I hope that helps you and anyone else experiencing this problem (happened to me as well).

Tony!
