I have been told that it was taken down due to a complaint from a copyright holder. Under the DMCA google has no choice but to comply. I mean they are selling it for 19.95 so the owners of the video might not like having it available for free.
Again, the DVD should have all kinds of supplements (and you can't easily play those through google anyway).
We need to send Netflix requests to stock this title. And Blockbuster mailorder, Walmart, etc. Wherever you have a membership.
I saw this at a film festival screening this year but would like to see the supplements so a rental makes sense for me.
