thanks for the link bb_mike!
also, i've noticed another issue (i'm pretty unhappy with this tv at this point but not enough to hassle with boxing it up and returning it).
when trumotion 120hz is on, it will smooth scrolling scenes for maybe 2 seconds but then i don't know if the buffer gets filled, but it'll stop smoothing for 1 second, then start smoothing again. i remember a review somewhere that mentioned this and now that i've noticed it, it's terribly obvious.
overall the 120hz on this tv is a joke, if i could do it again, i'd just get an lh30 since i won't be using the 120hz feature at all from now on.
