The video posting can be a great idea in some sense. I know a physics professor from MIT who posts his Rigid Body Motion videos and they were a huge hit among some of my friends though none of us were physics major. He will show live demos in the class and show how things really work. Someone like him can really stimulate students into an area like physics. I take a class where they make the videos of lectures online. They ask us to read the stuff and take quizzes from the videos. That makes people come to the class to grasp the topic, video alone doesn't help. Plus they pass sheets around and if you miss more than two lectures, you grade gets a hit.
