Google Videos not found

Hi there.
Thanks for this great plugin. Looks very useful.

I have tried to put in a Google Video. The link is: http://video.google.com/videoplay?docid=4663174070862353171

The video is available online. No issue there.
But ProPlayer brings up a video player, and then in the players says the video is not found.

Any clues?

Do I need use a different format of Google link?

Thanks… Jonathan
