Well, I have to agree that Camstudio and Fraps are the two best screen recorders out there. If you have the money (or a certain website) to get Fraps, it's very helpful for DirectX and OpenGL rendered windows...like games, movies...etc. Records that render window perfectly, in my opinion. Camstudio, I use for anything that isn't rendered, and it does a damn good job of doing so. So...in my opinion, Fraps & Camstudio are the ones you want to go with.
