THis one is for the program called 'Fraps'.
You can download a free trial.
Imho, it's still the best program to use, although, it takes a lot of your computer.
Ok here's what you do for FRAPS

This is the first page which you'll see, it tells you what version your using and the such.
What i do is have FRAPS start when i start the PC and have it minimizedv aswell so you can still take screenys and film.

On this screen you don't do much except the position of the overlay as in the fps.

On this page you set the film recording functions like the buttin you press to the fps (which i think you should leave at defualt; or just set atleast at 30FPS) also the place where it save all the recordings.

This page is for screenshots, on this screenyou set what button to press and where its saved (no pasting into paint FTW) and you can o it as much as you want, also on this page you set what file type the screen would be.
Here's the download link for anyone else who wants FRAPS unregistered (the one i got)
