As a novice, could somebody explain the correlation between frame rate and judder. I have been following the various threads about the Panasonic HDMi scandal and the FRC tests that Gordon did with the Pioneer and I am a little confused. If a plasma, such as the MXE1, is capable of a 50hz refresh rate why does it FRC all such signals to 100 hz. Is it purely to reduce judder and if so, why is it the opposite effect to a CRT where the 100 hz models have a lot more judder on fast motion? Also, why does FRC from 50 or 60 to 75hz induce so much more judder? With regard to PAL 50hz signals is it better to use premium video processing equipment on a HCPC to FRC and output a 60hz signal to the DVI input on the plasma where no FRC would take place, or would less judder result from outputting a 50hz, unmodified signal from the PC and allow the plasma to FRC to 100 hz? A big thank you to anyone who takes the time to educate me on these matters.
