To do this there are a few options:

Pixelwarp Edgeblend and Geometric Correction Software.

Sol7 Immersaview

Nvidia NVKeystone but it’s been discontinued since june 2 2009 🙁

VPT 5.1 video projection tool is free and very capable, but I haven’t been able to take a vga / dvi / hdmi output as a live input into it yet so it needs videos in a video directory to throw its layers on allthough this howto is a launching point.

MXWendler FXServer was designed for theatres and stages.
