Google Video Search is a software designed for fans of streaming videos. This tool makes it possible to browse through the online collection of Google Video without visiting the website.
The videos will be displayed in an explorer window (as if they were files on your computer) with all the necessary information like the title, type, duration, date, etc. You can watch the videos with your browser and you can also download them directly to your hard disk as AVI, MP4 for iPod, MP4 for PSP.
