Thanks Gonk for the info. I'm watching mostly HDTV and very little SDTV so if there is not that much improvement for HDTV that leaves SDTV and my aging VCR that would benefit from an Edge. Sounds like my earlier estimation of need for an Edge was a bit overstated. The need for a video processor should also be partly dependent upon the video processor in your display. From what I've read the processor in my Kuro 50" is pretty good further diminishing the need for an outboard processor.
