I suppose this is brainstorming for a problem that's been solved, I wonder if the flags of how much a viewer can see can be user-modified and stored in a cookie, and a few seconds before the video starts the viewer will get a reminder of what their preferences are, and what the video's rating is. If the video is "more challenging" than the user's settings, then of course the video won't play. And if the user hadn't set anything, they can just click "Skip the configuration, show me the video".
