The first comment appears to be accurate:

FYI, the 120Hz mode is an internal thing, and I suggest applying it only for sports. It creates new frames (one frame per real) thus for example the hockey puck is easier to track in a hockey game, however it creates issues with movies because the applied movie motion blur is optimized for 24Hz (24 frames per second) thus looks wrong at 48Hz (I know we're at 120Hz but it's actually 48 real frames for a movie, or 24 frames if not using the 120Hz motion smoothing mode).
(A 24Hz movie, or 30Hz video ends up as a 60Hz signal going into the HDTV. Then, if you apply 120Hz mode the computer in the HDTV analyzes several frames then creates NEW ones that fit in between the old ones. So, for example, if a hocky puck was travelling left to right it will make a new frame that puts the puck in between two of the original frames according to how it's accelerating.)
I'd still suggest looking at Amazon because there's usually good customer feedback, but I doubt I'd change my mind.
