Not sure this has been posted before. Although there are several programs available for downloading/saving you tube videos, I just discovered this one. Maybe some of you know about it already? It makes it very simple to save you tube videos to a number of different formats.

Take this you tube link for instance ( btw nice demo Donny )

then add the word "kick' ( no quotes just before the word you tube and yo can save
http://kickyoutube.com/watch/?v=qXkb0zGkxfc&feature=related

It's easy to do anyway if you have a Mac.
