I'd like to take an existing DVD (with a menu) and combine that material with new content on a new DVD. But I don't want to alter the menu of the existing DVD.
Let's say the disc I want to leave as-is is called Circuit City (as in the Apocalypse Now Complete Dossier Circuit City exclusive bonus third disc). So the newly created DVD would have a top menu from which you would select either "New Stuff" or "Circuit City". If "Circuit City" were selected, then the familiar menu that already exists on the CC disc would appear, with selectable content.
You follow me? Is this possible?
