Dear Michele,
  You can try one of the beta versions of VMD 1.8.1 which includes the
"VMDPREFERSTEREO" environment variable to help with the NVidia cards:

As I mentioned, we now have a machine with NVidia Quadro750XGL, plus NuVision shutter glasses, but I experienced the same problems mentioned by other people when trying the stereo visual, just the above/below scene with no real stereo.

Today I upgraded to their latest release, 1.0-4363 (24/04/2003) and vmd just takes up 99% of the CPU when resizing an empty window. The system no longer freezes but the program is not usable... I think the drivers might need some more bug-fixing. Next week I will test them on a machine running redhat8.0 with basically the same graphic card (NVidia Ti4200) where I happily run VMD with older drivers and I will let you know the outcome.
