uTIPu

This site http://www.utipu.com/ allows you to show folks how to do tasks on your computer. Sign up is free. With just a few clicks their software, TipCam, records a video of your screen and posts it for sharing. Downside is that the video is on the UTipU server but you can put a link from your Website to your video.

Look over some samples here.
