 And something very weird has been happening lately regarding these TVs. A lot of people have been complaining that apparently a Roku software update turned on what's known as action smoothing or motion smoothing mode, which on many TVs has been an option, but now for many of these users they say they can't disable it anymore and they're very upset. Now what this is all about is that films are conventionally shot at 24 frames per second, we know.
