Just a quick heads-up, I’m selling a bargain priced Optoma Themescene on e-bay at the moment. The Optoma HD-3000, it’s the video processor that many enthusiasts have in their systems for up-scaling 480p material. It’s also particularly good with 720p signals from an Xbox 360 or PS3 and with DVD’s and interlace material. If you want to see the quality of the scaling engine compared to other processors there are some good examples on this page http://retrogaming.hazard-city.de/
