Editing an iDVD '08 theme ?

[hamsinn]

I would like to use iDVD '08's "Bands" theme for my latest project, but I can't stand the fuschia graphic displayed in the bottom third of the layout behind the buttons. I have tried PlistEdit and Quartz Composer, but I can't seem to find the correct file or string I need to modify (if it is even possible) to change the color of the graphic. Any help would be greatly appreciated.

Thanks.
