does anybody know a good freeware tool for screen capturing? I need a tool to make a video like objarni did (see http://www.opentk.com/node/332#comment-1488).
I tested CamStudio, but I didn't manage to record my GameWindow in real-time with a sufficient frame-rate.
The other thing which comes to my mind is to use
GL.ReadPixels() after a game loop iteration and write it to a bitmap and make my own built video.
