CamStudio 2.0 is a free Open Source screen video recording application. It is great for recording activity on your screen for tutorials and demonstrations.

It works great when installed in Windows XP. However, the recorded video breaks up and isnt usable under Windows Vista. According to its Official Blog, version 2.5 is delayed but in development. Fingers crossed that 2.5 works under Vista!
