Downloading video clips -- I tried this and couldn't get it to work

Downloading clips from Google Video
Lifehacker.org describes how to escape out of URL encoding withn query string parameters to download clips from Google Video instead of streaming them in the embedded Flash player:
Go to Google Video and find a video.
View the page source code and search for the keyword ‘googleplayer‘
Copy and paste the videoUrl parameter (all of the characters after the keyword ‘videoUrl=’)
Press Ctrl-L to go to URL location bar. Type Javascript:unescape(”videoUrl”) where videoUrl should be the last parameter you have copied into the clipboard.
It should output the actual URL on the broswer, copy and paste that URL onto your browser location bar again to download the FLV movie.
Play it with a FLV Player.
This works in both Firefox and IE, and is hacky enough to be useful from time to time. And Google's safe - being in the source code, the key info's pretty safeguarded from programmatic access, which would turn Google's streaming service into one big download center. And the complexity of searching through source code and mangling the URL is probably complex enough to keep this away from the masses.
