I just found a place that you can download the DVD direct from the makers for free!
I finished watching it this afternoon and can recommend it. Some great macro and USB micro photography/video work and a thorough explanation of 'snap tentacles', their mechanics, evolution and later geographic distribution. As a bonus, at the end there's a little bit of another DVD they did at Rob Cantley's Borneo Exotics.
Here's the link;
