This is the 2nd post that you've posted that really should have gone in Happy Hour, not Tivo Coffee House. I'm not saying that no one here will answer, but that Happy Hour is a better place for non-Tivo discussions.
You need to go find a site that explains LCD refresh rates. Your questions show you have no understanding of what it means. Do a Google search for something like "60hz vs 120hz" and go from there.What exactly does a 120Hz refresh rate help with...that is noticable?
And do you need a special HDMI output to be able to do 120 Hz like a blue ray player...or perhaps a HTPC with a monster graphics card? Does TiVo output at 120 Hz?
A BD player (Blue Ray)Where do you get a 24 FPS video feed? From a cable channel playing "old movies"? From a VCR? From a DVD player?

And that's because movies are filmed in 24 frames per second.The streaming services have 1080P24 encodes(also720P24/480P24) . If you have a device that can output them in their native format.
It shouldn't vary because its playing from a pre-rendered source, not struggling to keep up with on the fly rendering of 3D geometry like in a video game. But I'm guessing the actual output FPS would probably depend on the video card, drivers, and probably playback software used by the HTPC.What happens when you have a HTPC play a blue ray disc or stream Netflix? Do you get 24 FPS? Or does it "vary the FPS" like what you see in games' FPS guages?
Well a the computer monitor has a "native" refresh it seems (mine is 60 Hz). But I'm not sure if that's actually a max or what. Because I'm pretty sure I've seen like "90 FPS" as well as "20 FPS" in the built-in game guage. So perhaps the rendered video is one thing...and the actual monitor output is another...unless 60 Hz is just for the Windows UI and "full-screening" allows computer monitors to go faster/slower with some sort of computer monitor specific electronics.It shouldn't vary because its playing from a pre-rendered source, not struggling to keep up with on the fly rendering of 3D geometry like in a video game.

I don't know if most video cards support 24 (or 120 FPS) over DVI/HDMI or if the drivers & video software would be smart enough to configure them in that mode when playing from a 24 FPS source.
(Hopefully someone more knowledgable can answer)
Unfortunately, it doesn't do a thing to reduce blur if what you have to display is a 60Hz signal, which is the best you can get from a 60Hz source such as TV transmissions (if you are lucky - some are only 30Hz) or a DVD. The blur is often visible in a single frame (pause your TV signal and take a look at it).As mentioned above, this type of question should not be in this Forum, but hey, I've got nothing better to do so let me throw in my 2-cents worth. 60 hz TVs refresh the image on the screen 60 times per second. This has been the LCD standard for years. However, one of the drawbacks of LCD TVs has been that when there is fast motion on the screen there is a slight blur in the video. They now have 120 hz sets that display the image twice as often, thus reducing the blur considerably.
For Blu-Ray, that depends on your hardware. I have a PS3 for my Blu-Ray player, and a TV (and home theatre system) that support 1080p24. This means that when I watch a Blu-Ray I get 24fps.What happens when you have a HTPC play a blue ray disc or stream Netflix? Do you get 24 FPS?
I'm pretty sure the games are talking about the frame rate of the data being updated in the frame buffer (i.e. rendering), not display refresh rate. I just checked an old asteroids 3D game that I wrote many years ago on much older hardware, and it claims to be rendering at over 2500 fps on my modern hardware when set to immediate render mode.So perhaps the rendered video is one thing...and the actual monitor output is another..
For what it's worth I personally don't care for that motion smoothing / interpolation effect and turned it off on my TV...The other effect comes from the fact that some TVs will actually interpolate a new image in between the two transmitted frames. This generally works quite well, although there are occasional artifacts created by this process.
I'll second that. In fact, many people (me included) feel it makes everything look like a cheap direct-to-video production. I keep it turned off on my sets that have it.For what it's worth I personally don't care for that motion smoothing / interpolation effect and turned it off on my TV...
