YouTube >> iPod

Unlike google video, youtube doesn't provide option to download video, one of my friend forwarded me link to Stephen Hawking's Origin of the Universe lecture at Berkley, i wasn't able to control my urge to download to my pod, after few mins of search ended up using this site to download youtube video in mp4 format. I'd highly recommend the site, just for its simplicity of doing all with no software to install in my machine.
