I dunno the program you are speaking about, but three quick thoughts would be that:
A: It doesn't like OpenGL 3D rendering and the program wants to capture DirectX screens and video overlays only.
B: It will work with OpenGL but only at certain screen resolutions so you have to match the settings to what it requires.
C: It is a hardware capture/playback issue with your gaming Video Card.
I haven't tried GameCam myself, but is this the same program that Storm_Knight recommends in his Demo Editing Guide ?
A lot of people who video capture from the game seem to like using FRAPS . It's free, but you can only capture 30 second clips at a time and it has the web link in the upper center of the screen... Unless you register it for $37.

Yes, it's the same thing. I can't get it to work. I'll just use Demos and screen dumps.
Anyone know how to get GameCam working with CoX? GameCam Lite would crash the game & GameCam doesn't seem to recognize the video. The preview screen is black and it records black. I also have the top quarter of my screen blacked out.
