Tying Replay Videos Together As A Roadmap for Viewers

I am looking for a way to prevent my replay viewers from skipping around from talk to talk. The event was produced as a roadmap for success so if they skip around the videos they will not get the full impact, in terms of information flow that is set to educate and facilitate true transformation. They can skip around from video to video after they watch the entire series initially—I am hoping have it stay in sequence and, perhaps, pop up the next video once they complete the prior one. If they do not watch a video completely, then it will pop up when they revisit the replay.

I know this is a lot to ask but it will give us as event producers opportunities to ensure our audience is learning in a structured way, based on content and also allowing them to revisit the content as they choose once the system shows that they have followed the structured sequence on their first time around.
