Hi Alvin, first thing to check is have you enabled 3D on the Nvidia control panel? If after setting this up, it has some included 3d pictures to test out. If the test is succesful in producing a 3D image, now is the time to fiddle with PowerDVD10's setup choose Nvidia 3D vision as the 3D output format then open a half SBS file or Bluray 3D. If this still doesn't work you might try PowerDVD11 or Total Media Media Theatre 3 or 5 again setting Nvidia 3D vision as the viewing environment.
If you are unable to turn on 3D on the Nvidia control panel, you will need to install the 3D vision usb IR emitter emulator hack to enable it.
With regards to the 2 left/right full SBS files you must use stereoscopic player to play them just set as viewing method - Nvidia 3D vision. I've included stereoscopic player with the 3D files I copied for you.
Hope this helps.
