What is a good screen reocrding program?

I want one without a setup for it. I want to record it for minecraft

You can try CamStudio: http://camstudio.org/

Alternatively, you can try Fraps: http://www.fraps.com/

Those are all pretty good screen recorders [screencasters]. You can try Screencast-O-Matic which also supports Mac and Linux: http://www.screencast-o-matic.com/ [Although I'm not sure that does exactly what you're looking for, the other two above definitely do the job].
