This is not the DVD Player offered by 3DFX. This one works! Two files are required to complete the installation "3DFX-Voodoo-3-DVD-drv.zip" & 3DFX-Voodoo-3-DVD-plr.zip". Installation instructions are in the readme.txt file and the install is automated so it should work out of the box. This is not a demo nor is it shareware.
