This is not the DVD player offered by 3DFX. This one works. You must download two files "3DFX-Voodoo-3-DVD-drv.zip" & "3DFX-Voodoo-3-DVD-plr.zip" to complete the installation. This is not a demo nor is it shareware. Instructions for installation are in the readme.txt file. Installation is automated so the system should work out of the box.
