One of my collegues asked me to download a video from video.google.com. He tried to download a file, but it is not in a AVI-file it is a VideoGoogleFile 
I remember me that when you download it using Firefox and Linux it will offer you a AVI-file… 
So here comes the trick… change your webbrowser ‘User Agent’ string into a Linux one, ie:
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7
The easiest way to do is:
- Install Mozilla FireFox;
- Install the User Agent Switcher
- Add the useragent string:
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7
For more information regarding User Agent strings take a look at Wikipedia.
