Now you should only need a 3D capable video player such as Powerdvd 11 or stereoscopic player. Apparently you only need the NVidia 3D kit for playing games in 3D, not for watching videos or BluRays.
You run a HDMI cable from the computer to the projector, either as a second monitor or as the primary. Make the video player software play on the projector screen, maybe have to drag that window and then full screen it. It helps if you can work a mouse while watching the projector screen.
The video player software should recognize that you have a HDMI 1.4 capable 3D display. If it doesn't, you gotta make it recognize it. Sometimes reboot, or sometimes log on again (switch user).
