Reauthoring a DVD to loop a video
 

Here is the problem.
I have software that will create a tribute DVD with out any outboard DVD authoring software.
What I need to do is reauthor the DVD, keeping the existing menus etc..., so that the main video will loop until stop, menu or title is pressed.
Anyone have any ideas?

I could recreate the DVD in Encore DVD or DVD Lab Pro but redoing the menus is a real pain.

Thanks,
