Those with a 120hz monitor should check out Smooth Video Project. http://www.svp-team.com/wiki/Main_Page Basically it turns 24/25/30fps video and interpolates the frames (fills in the motion details) into whatever maximum refresh rate of your monitor is. In a nutshell, if you've seen those 2000hz tvs or whatever that smooth out the picture, it's a software (and GPU accelerated) version of this. Admittedly it does introduce some artifacting on high motion scenes, but, it doesn't add that slow mo-high mo rubberband like effect that is often witnessed on those 2000hz tvs.. It keeps the motion at a very smooth framerate. There are a few commercial versions of the same thing but this is free. ie, Splash Pro (which doesn't even do 120hz ) That said, SVP is a set of filters which do the conversion and is not a video player in itself. There's a minimal install and a full install, with the full install including Media Player Classic - Home Cinema. I'd recommend installing the full thing and including reclock (reclock syncs video and audio together so it significantly reduces tearing).
