I have my OPPO's video connected directly to my Sony HDTV with the supplied DVI/HDMI cable. I don't know which TV you have, but all that I am aware of do their internal upconversion to whatever format they need. Once again, doing upconversion in an audio receiver makes no sense for me with any of the newer HDTVs.
