I stumbled across "itunes university" (part of the itunes store) where there are a fair number of free videos available in Chinese. Some are very dry (there's a whole university course in accountancy), but a lot are pretty decent.
I haven't watched any in great detail yet, but these two on a cursory glance looked interesting (search in itunes for them):
"我的太阳创新360" has a whole lot of short programmes on everything (magic, art, etc), and have lots of footage rather than being someone talking at a camera. Not classroom based.
"中国课堂“ also looks interesting. It's primary school kids' lessons which have been filmed. Them doing maths or whatnot. The language is a lot easier!
Might be worth a look.
