For some reason people fail to see that when there is a full movie on google video, there is someone you can contact and have them take down the content.You can hold someone accountable. See what happened with youtube and viacom for example.
Try getting a torrent site to stop tracking copyrighted material, or try to find everyone that is sharing the content to stop.
And since I know someone is going to say that you can get torrent sites to stop tracking:
