XVidCap
If you need to capture screen video for training, demonstrations, and the like, try xvidcap, a small and simple utility. When run, XVidCap shows a toolbar and underneath, a resizable window. Anything that takes place within the window is captured and saved to an MPEG file. Controls are intuitive enough, so you should have no problem. My only beef is that the software seems to generate plenty of popping in sound.
