I'm hoping to purchase the 53" HD5 Pioneer set very soon. I've heard the line doubler on this set is one of the best. Is the line doubler active on all the inputs? I have a non-progrssive DVD player which I can send straight to the TV as component or S-Video, or go through the Denon 3300 as either of these. I've heard the line doubler isn't active on the component input so I'd be better off using the s-video input to the TV to take advantage of the line doubler. Is this true? Also will have the rest of my video inputs (digital cable, OSD from receiver, etc) coming in through s-video also.
