As all Tech Ed 2007 attendees know, 3 months after the conference, the sessions appear in the mail on several DVDs. Last year, I jumped through a few hoops to convert the fragmented sessions files into a single *.wma file that could be played on my music player. It was a bit frustrating.
This year, I was pleasantly surprised to find that all sessions on the DVDs come with an extra audio file (*.wma). This means, I just drop the .wma into my music player with the rest of my podcast queue and listen on my commute, while mowing the lawn, etc. Good show, Tech Ed committee!
