24 frames per second - for tv this is basically the level of frames would portrays smooth movement etc.

60 would obviously be 60 frames a second which in theory would be more fluid than 24 but is probably not a huge improvement vide wise.

Most movies are filmed in 24 fps. 60 Hz TVs have to use a process called 3:2 pulldown (Wikipedia it) to display 24 fps sources, like movies. All the talk about this probably relates to the new 120 Hz TVs, which can display 24 fps (movies), 30 fps (TV shows and games), and 60 fps (games) "nicely" (in that 120 is the lowest common denominator of 24, 30, and 60 -- if you looked up 3:2 pulldown, you'd know why this is good).

There might be some parts of my explanation that could be explained better, but I hope I got the gist across.

Great explanation. Does the 52" Samsung LCD 1080P have the 120 Hz?

I think that most of the new 120hz TV will not help with judder. They either don't accept 24fps signals or they change it to 60hz then to 120hz, which makes it kind of pointless.

I'll bet the next generation of 120hz TVs will be better in this respect.
