JohnMeyer has posted an efficient Vegas script which allows the user to batch archive VEG files and their media files pointed to by the VEG. (See his post of 5/24/2005 9:09:00 PM for more details).

Is there a comparable script available (or possible) which performs an analogous function for DVDA3 projects?

It would be terrific to be able to archive all of the various media materials and other files that go into the construction of a DVD.
