I have been trying to get this working with no joy 
The status flag is set either when the last frame of the slide is met or on moving to the next slide. I cannot find a way to set it by a script or action.
The problem with restricting the ToC navigation to viewed slides only is that you can only view the slides visited in the current session. For example if I have 20 slides in a topic, view 1-5, exit and then return the first 5 are recorded as visited and the project plays from 6. However you cannot view 2-4 unless you go back to 1 and start again. If I complete the course the same thing happens. That going to be very frustrating for anyone who have completed it and wants to view a slide again.
I have also tried using multislide video, with one video per slide and then disabling all the button except play and back. However this does not solve the ToC problem and makes rewinding/reviewing content difficult (you cannot use the progress bar but have to implement a button which is clumsy).
Currently I cannot see a way to implement a framework that prevents the user from clicking through the content then completing the quiz.
I am stuck and hope that there is a solution.
