perhaps a pdf version of the book as ROM content, and save hours/weeks/eons reformatting the book into menus? Make 1 menu that refers to the pdf, eg. “Load this disc onto your pc’s dvd player…” so folks know it’s there.
I’ve done over 60 retail releases so far with no replication issues. It’s not as strict as Scenarist and lacks a few things like DLT support, seamless angles, etc., but it’s the only other pc dvd authoring program with full scripting capability.
