I am trying out different free screencasting tools to see which one I like the best.  Here is a link to a screencast I created using Jing about the snipping tool in Windows Vista:

Snipping Tool

Jing is a free screencasting tool and you can upload content to your account on Screencast.com.  You can also save the screencast as a flash file.

I should warn you that it is rough and in trying to capture my screen it created a very large video.  I will try and figure out a better way to do this.
