I have the Hitachi 43UWX10b 16:9 RPTV with a Panasonic RP-56 progressive scan player hooked to it via component cables. I was rifling through the manual and noticed this: "Component color type: HDTV - Use for High Vision signal Y-Pb-Pr from HDTV set top box. SDTV/DVD - Standard Definition Television or DVD Y-Cb-Cr." I currently have it set to SDTV/DVD. However, I notice that the component outs on my Panny are labeled Y-Pb-Pr. Since this is the case, should I actually have the TV set to the HDTV component color type? I also have an X-Box hooked up via component and same thing there -- the outs are Y-Pb-Pr. If anyone can explain this to me, I'd appreciate it. Also, just what the hell does NOISE REDUCTION actually do?
