Learnoutloud.com is a nice source for audio and video with many topics that deal with education. There is a mix of free and pay resources. Most are professionally produced. I did a search for “Lessig” and found 125 links to my favorite open-source-copyright lawyer.
The only problem I have with the site is that it favors Real Audio. I would not install that player on my machine for anything. Fortunately there are plenty of plugins that enable you to play RAM files in most of the popular players.

I like Real Alternative (http://www.codecguide.com/about_real.htm) as an alternative to RealPlayer. It doesn’t try to install other software. It doesn’t take over your computer as the default handler for all media files, and it doesn’t nag you to upgrade it.
We’ve also been playing with Foxit (http://www.foxitsoftware.com/pdf/rd_intro.php) as an alternative to Adobe Reader. It doesn’t take forever to load, and isn’t constantly trying to update itself.
A great resource and there are some MP3 files to be found there as well
