This is pretty poor considering that you've got the NVidia 3D glasses. Perhaps the NVidia drivers only provide a hack for 3d support in 3rd party apps, as they do for games. I would be worth contacting NVidia about it as frankly selling hardware but not supporting quad buffer stereo in the drivers is just plain incompetent/fraudulent. Robert.
