I could show you 100 fps but if there where only 4 different images 
displayed the illusion of motion would be no smoother than 25 fps. You only 
get smoother movement by increasing the number of different images 
displayed.

So if this hvfhd only repeats each frame to get a higher frame there is no 
increase in smoothness. How ever if they take each field, upscale it and 
encode as a frame that would inrease the smoothness.
