I just got done watching a TV program on PBS that I have a TiVO subscription to, "Land of the Dragon"

which is about various facets of chinese culture(s), and the most recently shown episode had a bit about the Tea Horse Caravan and cultural exchange, mostly through how Shaxi village serves as a good example of this.
There have been several other episodes of this program that highlight tea, including one on tea culture, gongfu tea, and teapot making. I thought I'd share. It's worth a TiVo if you're interested in China, particularly in its arts & ethnic minority cultures.
Any other good TV programs on tea out there?
