Script Summary: Circumvents the region lock on Google Video
This script should work for all free videos on Google. It uses Google-Translate as a proxy, but unlike other scripts it doesn't show a frame and the experience is very close to the original thing that you can only get in some countries so far.
You should be able to use almost all Google Video features including playlist and download even though your ISP is still banned from this new Google service.
The Google Video Player Plugin does NOT work however, since it only works on "video.google.com" and no other domain. There are modded versions of this plugin, that circumvent this limitation (since it is release under the GPL).
