Common Sense: "Yeah, you could. But don't. Just don't. I don't want to watch computer-interpolated content."
TV Manufacturers: "Even if the result would make film look like video? That's awesome, man!"
Common Sense: "Um, no."
As for the 120hz, it CANNOT be turned off. And, since it's the refresh rate, it will refresh the picture twice in the same amount of time as a 60hz TV. That's why all things equal, a TV with 120hz will ALWAYS look better to most people than if the same TV had a 60hz, even when the 120hz has the motion processing off.
They all have motion processing which can be turned on, turned off, and/or adjusted somewhere in between. Sony calls theirs Motionflow, Samsung calls their AMP (Automated Motion Processing), and I'm not sure what LG calls theirs, but they all pretty much work the same. Some a bit better than others.
