Just got finished watching A secret life of Walter Mitty and was messing around with the auto motion plus. There is a scene around the 36-37 minute mark where he is running out of the building and there are a bunch of Time magazine covers on the wall behind him. At first I had AMS off and the pictures behind him were shuddering like crazy, then I tried smooth and it was almost perfect, then standard and it was the same as smooth. Later on in the movie I changed it to clear and towards the end of the movie there's a scene where the plane is landing and the city is in the background and there was shuddering again. I paused and put it back to smooth and then standard and it was clear again.
Just an observation I thought I would share in this thread, there's still a lot of settings I need to tweak, but I'm still really happy with the tv so far. I did notice a little flash lighting in the corners, but when I get up and close on the tv they seem to disappear almost like its dependent on the angle I am viewing at, weird I know, but even so it wasn't enough to justify playing the tv lottery yet. I'll be looking closely over the next few days/weeks.
