I have a software demo movie with a 10 item index page (text converted to Symbols) and a corresponding number of scenes where I would like the index to indicate which scene(s) the viewer has already looked at.
It could be either through changed font colour or, more elegant(?), with tick boxes showing the visited index items.
The movie is set up to automatically revert back to the index after a scene has played to the end but the viewer can view the items in any order he/she wishes.
I do not want to mix my movie with an HTML index page which (I think) would have been a simple solution to the problem.
The answer should (preferably) work both on the Internet and on a demo CD.
