New Method: The easiest method now to download google video is to use online video download service to expose the real URL. Old Method: Good news is that Felipe Cepriano over at FelipeCN has found a quick way to download Google Video. The key is to unescape the parameter of the Google Player URL by using a javascript function. In simple instruction:

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.
