All the options Chewtobacca mentioned are possible. But for now this thread is for researching issues related to seamless branching/storylining.

Once the 'Preservation' forum thread is created then this might all change as the project specifics get discussed. The projects inspiration is the tv format and separating out the elements for the convience of production, is something I can afford to look past at this time.

I understand, and am sorry for not really answering the question. :-) I did try to find out how to do this a while back, and could not find any precise information. (To be clear, I intended the three points in my first post to be successive steps, rather than different options.)

I believe DVD Lab Pro is your best bet for seamless branching.
