playback seems too zoomed

RPC 4
Vista

RPC seems to be too close on playback. i recorded an online vid just to practice and when i play it back the guy talking has the top of his head cut off. I changed to record full screen but still seems too 'zoomed' for want of better word. When i doublecheck the original i can see his head and space above

Thanks

Make sure your system is not set to zoom in or that the resolution is not different than the standard.
