Issue with Restricted Navigation + Resume Saved State + Replay Button

I think I follow. You describe what should happen, and you say there's a conflict, but you don't describe the conflict of what should happen but doesn't, or what shouldn't happen but does. Does revisiting the course not resume the video from the exact point where the learner left off?

I understand that the course player's restart button won't restart the slide, but if you need a way to allow the learner to replay the video after completing, how about adding a button on each video slide that flies in right at the end of the video, and if the learner clicks the button, it fires a trigger that "jumps to" the same slide you're on. The slide will start over from the beginning.
