I would say all video source have judder.
Just the matter of more visible or less visible only.
All movie in Bluray 24p format has judder, because of the 24p low frame rate, which in nature is not very smooth to our eye.
30p format will has less judder.
The 60Hz output will smooth out both 30p and 24p video source.
This can be set on the Bluray player, Media player or Computer/Laptop, not on the TV.
Set the output to 60Hz.
I don't quite agree that 24p at 60Hz will have smoother motion than say 72Hz/96Hz. It really depends on how the set is doing the refresh. Some modes do weird things.
If done correctly, refreshing 24fps at 60Hz via 3:2 pulldown will show some irregularities. However, some displays do it better than say 24fps to 72Hz. It all depends on what is going on.
It also depends on individuals, some are more sensitive and its important to be able to differentiate motion issues with just phosphor trailing/refresh issues.
Panasonics handling of 24p material to 96Hz gets motion correct, but does cause some flickering and the way the draw the images can cause some individuals to see it as unnatural.
Its actually due to the way they refresh where it exhibits a little more false contouring that some are sensitive to. Also, getting ur calibration right, can reduce the effect to some extent.
Pioneers method of refresh and their 72Hz was the best I hv seen but their PulseWidthModulation (PWM) techniques that help to mask the false contouring and banding does cause a little more dither than some individuals find grainy. Panasonic draws a cleaner picture but the other side effects rear their ugly head. There is no perfect implementation. Panasonics became a little more apparent when they introduced the 3D. They made some adjustments to how to refresh in the later series that caused other issues. Samsungs have their problems as well. So u choose what is the least problematic to ur eyes.
Same goes to LCD based displays, some of them do it better but sacrifice something else.
