University of Washington Television filmed a segment on foldit a few weeks ago for their TV magazine UW360. This is playing on the Seattle area UW public access channel at various times in the next couple weeks, but it is also online.
You can stream it currently at http://www.uwtv.org/uw360. It will be archived at http://www.uwtv.org/programs/displayevent.aspx?rID=32405, which also allows you to download it in various formats, including just listening to the audio. The foldit segment starts at 0:52.
