Having made a video that was sold on DVD and been a TA for a university course, I'm pessimistic that any university lecturer would bother with the extra work to make the videos good. I had no idea before I did it, but video editing is hugely time consuming. I'm guessing to make a really good video lecture you'd have to spend about 10-20 hours per lecture. Hours prepping the slides, the room, coordinating 2 camera guys, syncing audio after the fact, editing the video, etc. sketerpot's comments are great, but I'm a pessimist. With current tools it would take too much work from the lecturer to make truly good videos. My point was that at a bare minimum if you somehow could make what's appearing on the board visible in the video, you'd at least make the experience as useful as being in the class. As it stands now, you're better off just listening to the audio. However, there's a lot of room for technical innovation. Software to help automate the production work needed to make good lecture videos would be a cool startup idea.
