I just got my new RP91, that I exchanged for my SD5700, hooked up on my Toshiba 50HX81 and I am having a problem. I was trying to calibrate my set to the RP91 with Avia and I noticed something strange. On the sharpness adjustment on Avia the top middle line was jumping up and down as was the side lines on the left side of the screen. This was in progressive mode....when I turned progressive off it stopped. Does anyone have this combo or know what could be wrong. I read in the manual that there was some type of copyguard protection on progressive output. Is there a way to get around this? As of right now I AM PISSED!!!!
