That's quote true - but one could also look at the videos as a means to an end, right? Taking the marriage analogy, it's like getting into a live-in, to see how marriage works. But then again, I'm the last guy to talk of relationships!
IMHO, a video course needs more than just videos to get coders to get their hands dirty. Practice problems, or just open-ended assignments. That's something I am working on.
At any rate, thanks, mate. This was a pretty intense and interesting discussion :)
