I’ve just ordered a new video processor from DVDO called the iScan HD. This device allows you to connect your various video sources (DVD player, Xbox, HTPC, VCR, Cable, etc.) to an HD display device that uses DVI (plasma, projector, etc.). It also switches digital audio sources and uses some algorithms and custom hardware to scale and process the video to get best results on your output device. I’ll report back with the results once I get it.
