I'm having some major lag issues for GH3 and my hdtv. I've been trying to calibrate it through the option menu but it barely does the job. I'm playing on an LG HDTV that's connected to a Samsung home theater system and my wii is connected with component cables. I beat everything except the last setlist on expert on an SDTV so I know it's not me sucking (i test out each calibration to the first song Foghat - Slowride). everytime i calibrate it the game gives me a different setting, anywhere from 0ms to 71ms. I've tried calibrating it SEVERAL times over to try and find some consistency but it usually jumps around.
if anyone has any suggestion please please tell me as I would hate to put this 90 dollar investment to waste.
