Before everyone jumps on this to me there are a couple of things.
1. Did his TV have tru-motion enabled, meaning was it before the update?
2. The type of tru-motion he seems to be describing is just one of the selections, ClearPlus. That one uses the scanning leds, in addition
"The TruMotion system control both frame interpolation (that calculates new images) and scanning backlights. When set to Clear plus the frame interpolation system is still active along with the scanning backlight system."
3. When I turn on trumotion, (I don't use clear plus mode) there is certainly a difference in smoothness, so whatever is happening works. Camera pans are smoother, looking out a window of a moving car the background becomes less blurred just as my last TV with motion control.
I'm not saying he is right or wrong, but if I am getting the desired results I guess I don't care.
