I've just watched two of them (8: Data Structures from SICP & Graph Algorithms from Algorithms) and enjoyed them. The format of the videos is nothing special (camcorder on a tripod at the back of the room), but the teachers are very good, presenting complex subjects clearly. The videos alone seem an excellent reference & resource. The accompanying materials (handouts etc) are sparse but good accompaniments. The courses were taught assuming reference to a textbook, so they're not 100% self-contained.
I watched the "AI" course about a year ago. 4 lectures, each about an hour and half. They were very good, and I strongly suggest watching them (if you aren't already familiar with AI).
This is fantastic. I'm glad that there are such detailed resources available for guys like me who want to get a thorough understanding of topics like these, but didn't go to MIT or comparable schools. Thanks for the link.
