HLdan, I don't believe your anecdotal evidence to the contrary puts you in a position to so aggressively defend pixel orbiters.
But I'm interesed to know, what do you see as special about your pixel orbiter? How has this function been improved by Panasonic? I ask because there are countless reports about how ineffective they are all over AVS.
How many hours did you have on the panel before and after enabling it? Ah, but you can't control for this, so this is an uncontrolled experiment.
Speaking of which, did you control for things like contrast ratio and peak luminance when you switched modes? These factors will affect the severity of IR.
Anyway, certainly seems it may be doing something for you and that's fine, but why dont you try switching back to THX mode for a few weeks and let us know how it goes?
