PC Game Screen Recorders

Ok Hypercam just won't do it...
I downloaded Hypercam and Cam Studio and Camtasia trial and Game Recorder.... but none of these screen recorders can record THPS 4 PC Demo... HyperCam does but it does some blinking thingy flashing and all that and the other are more wacker than hypercam so can anyone help in screen game recording... also THPS demo automatically goes full screen (which is center screen with black out line on Toshiba Labtops) so help anyone?
