The multi-angle option i'm attempting to work through. The main hurdle just solved for a 10 minute section is the multi-angle video needs to be almost exact. The GOP (Group of Pictures) the i,b,p frames need to be consistant, between sources. Which is easy if the two videos matched but these do not share any one shot at any one time. Figured out how to auto insert thousands of compression markers so the two videos which wouldn't normally share common GOP characteristics, now can. About to find out how bad that affects the video compression. I'm playing with the minimum being in the high 3's. So that an H.264, 2hr can fit in 4gb so two full movies can exists in the multi-angle video. Slow progress, but getting closer to working.

Anyone know any other multi-angle things to consider when making the DVD?

In several wiki pages, they say that the SW dvds have multi-angle material, but don't remember hearing anyone mention it. Is this correct? If yes, which release:

Chapters and angles
DVD Video may contain chapters for easy navigation (and continuation of a partially watched film). If space permits, it is also possible to include several versions (called "angles") of certain scenes, though today this feature is mostly used—if at all—not to show different angles of the action, but as part of internationalization to, for example, show different language versions of images containing written text, if subtitles will not do (e.g., the Queen's spell book in Snow White, and the scrolling text in the openings of the Star Wars films). Multiple angles have found a niche in markets such as yoga and erotica.
