"Standing With Stones" is a set of documentary episodes that I understand was shown on British television. I was able to obtain the DVD from the library and have spent several evenings watching the entire series.
The trailer for the series is embedded at this post
in my blog.
The website for the program is here
I highly recommend this for anyone interested in the prehistory of the British Isles. If your library doesn't have or can't get a DVD for you and you don't care to buy a copy, the individual segments of the series can be found at this YouTube listing
