I bought and have received the DVD set. So far, I've only had time to watch the first three episodes and I have no regrets about the cost. It is well done - a class act for sure. Also, tons of information and really interesting stuff so far. I will be giving this some time at our group's functions too.
As to PBS, I have searched and searched and am not able to develop anything definitive either. Mostly, I got the DVDs as I don't think there's ever been a "series" of which I managed all episodes even with full scheduling information, so I just bought it as soon as I heard about it (after watching the snippets on their site).
I'd recommend it for sure.
