I notice a few of us here have got the same or very similar set-ups - Pioneer Plasma (434 or 504), AVR300 and DV79. After just shifting my room around, remounting the plasma and having set everything up again I don't seem to be as happy as I was previously with what's coming out on the screen from the DV79 over HDMI. It all seems a little grainy than it was before, and as for the quality I purchased it on from the demo, for some reason it's nowhere near. Is it worth getting the new media box from Pioneer and giving the YUV over HDMI a shot? What settings are people using on the plasma and DV79 for best results? Cheers in advance. ............ off to phone Pioneer again.
