OK based on reading your advice several times i think i got it.
1. So i created individual timelines for each video.
2. I populate each with all the assets needed for that video in any situation
3. I create chapter playlists of the assets i will need from each time line for each menu button
4. then i create a playlist of the chapter playlists to play what i need for that particular combination.
If that is correct....then i am at trying to figure out the best compression for the audio to not go over alloted 4.7gb
I really appreciate this help :-)
