That site looks great. I was looking for introductory literature classes. I just wish they had ripped the audio tracks and made mp3s so I could listen to them, too.
A few other resources, for those interested:
http://www.khanacademy.org/ Khan Academy has 1400 or so youtube videos on general knowledge. I have personally used them to ease myself through Multivariable Calculus. The quality isn't the absolute greatest, but they were all made by the same, incredibly dedicated man. You have to give him props for that.
http://librivox.org/Librivox is an open source audiobook project with hundreds (thousands?) of recordings of public domain books. There was a thread about this a little while ago with no responses, but I think it is worthing mentioning this again. I have used this resource during my commute many times. Again, the quality is variable, but it is free, open, and close to comprehensive so one can't complain too much.
