Hi Jill,
  Ok, now you're cooking.
In order to get the Eye3D glasses to work, make sure you're running in the
24 or 32-bit color modes on the NVidia card, and then select the
"scanline interleaved" stereo mode in VMD. Once you've done this,
then put the Eye3D emitter box into "line blanking" mode which is the
3rd stereo mode (if I recall correctly). Once enabled, put on the glasses
and every other scanline should be left eye or right eye. You may need
to press the left/right toggle button on the emitter since there's no
guarantee which way its set since it depends on the position of the VMD
graphics window on the screen, but this is easily remedied. Give that
a try and let us know if you need any other help getting it going.

Thanks,
  John Stone
