Hi

http://www.bbc.co.uk/iplayer/page/item/b009pg5g.shtml

Here's a recent BBC documentary on meditation and it's effects on the body and mind including a bit about MCBT, mindful cognitive behavioural therapy for depression and structural changes that have been measured in meditators.

It's only there for about 6 days to stream but you can download it.
