I know about it, but I haven't looked yet. In the large episode group, there are 658 episodes. The YouTube listing doesn't make it easy to search for a particular episode, though, and YouTube's compression is horrible.

I face the same dilemma on Bob Ross' The Joy Of Painting. I would love to download them, and they are on YouTube, but the compression makes them look really bad. Well, that, and I'm not sure how to download a huge number of vids from YouTube like that. :/
