 What these smoothing modes do is add extra frames that are created by the hardware to pull the frame rate up to the maximum for the TV, often like 60 frames a second. And this causes what's often called the soap opera effect, in that the movements in the films become oddly smooth and looking much more like a classic daytime videotape soap opera than a feature film. And there are some people that like this, but I think it's fair to say that most movie fans, especially classic movie fans, really dislike it. I certainly dislike it.
