They also have a Roku channel and an iPhone app. The iphone app lets you do audio only to cut down on BW. But with a course like Understanding Greek and Roman Technology (one of my all-time faves), the video is pretty invaluable.

Wow, same here. I have an audible membership and several unused credits. After browsing the great courses (which I hadn't heard of before this), definitely going to try one.
