aka motion interpolation, I usefully use this technology during watching downloaded program like infinity challenge, running man, and the other brocasting programs etc.

but, this technology has some disadvantage against making movie smoother. first, it takes much resource mainly of CPU. even though there is some skill enabling GPU to calculate the date required the interpolation, CPU still be many part in this frame doubling.
second, using it during watching movies, there remained some dirty ghost images on movie. I can't explain in detail about this problem because it's difficult to explain this phenomenon to your guys without some example pictures.  

Anyway, despite some problems of it, it's very good technology if you don't like low-frame movies. for example: 30fps->60fps, 25fps->50fps

if you guys want to use this, refer to this address: http://www.parkoz.com/zboard/view.php?id=my_tips&no=15133 [Potplayer forced 60fps truemotion effect]

If you want to run programs correctly, I recommend that you guys should follow the guide line for installing frame doubling programs. because I was annoyed by errors such as sudden c++ errors on playback.
