It wasn't long ago that I was talking with my roommate about how it was only a matter of time before someone was able to get the HD-DVD add-on for the Xbox 360 working with an ordinary PC. Well that day was today and surprisingly it was my friend Dan at UNEASYsilence that was able to pull it off. All it took was finding it right Windows drivers and an HD-DVD compatible DVD player application. The HD-DVD add-on will run you 199 compared to set top HD-DVD boxes that cost 500 and up.
