Worth a trip to the other hemisphere of earth, I suppose! ;D ...sorry, I couldn't resist! I've never heard of such a problem in any other context, though. Are you talking about the turntable gimmik from the options? If so, you may notice that there are no other settings for it, but it does respond differently to the free camera mode. Maybe if you turn your model upside down and then the freecamera upside down, you could achieve a rotation to other direction.
