I have been using my Hitachi's dvi input from a denon 2910 for a few months now and out out of interest connected some component leads to my tv for comparison. I was shocked to find that component gave me a better picture than hdmi-dvi. Better colour,less noise and in some cases sharper picture etc. Hdmi also [in comparison] gave me a green tinge more background noise i.e clouds, sky and walls.to any films I watched even when using 480p and 1080i. I would never have known without the comparison with component. Why is hdmi considered superior? Maybe its just me who thinks this.I don't think it is suitable for sd dvd movies which are available now.
