How about using to cameras. One for on-line streaming and the other just for proper recording the lecture, even in HD. It would be a very good basic material for the future DVD with the proper menu and index so you could be able to find all the info you are looking for. Your lectures are the best training guides I've ever seen. I can't watch the lectures on-line unfortunately.
Maybe instead of DVD someone can work on some kind of app for mobile devices with all the advantages like the index of content so you can search for the subject you are interested without getting through all the material.
Just my wishful thinking
