IDVD with multiple sub chaper selections

Question

I have created an iMovie with small (1 minute or less) presentations of 30 speakers. On a single iDVD I wish to have the following:
1. The ability to play the entire iMovie in the order it now exists.
2. A Selection of:
a. speakers from occupation categoires (approx 10 occupational cagegories with 2-4 speakers each)
b. categories of speakers based on their content (not necessarily by their occupation. This would be approx 6 categories of 4-6 speakers each.
In other words, a viewer would (if desired) see all of the speakers 3 times: once in the order of the original video, a second time by selecting from the occupational groups, and a third time by content of their presentation.
I have made idvds in which their were selections (made by chapter markers within iMovie) but these always were in order of the presentation. Now I want to do the above, a more complex task.
How should I proceed?

Answer 1

Boy, that IS complex.
I think you'll need to do 3 separate iMovie projects edited to display in the categories that you want, or one long iMovie containing 3 separate consecutive movies accessed by chapter markers.
Perhaps someone else on this forum can come up with something better.
