Hi noggin. Can you confirm that this issue will be less noticeable on a 120hz tv? In theory such tv's wouldn't need to use 3:2 pull down, right?

Ok thanks. Yes I meant from a 24p source. Looks like I should get a 120hz tv. Thanks.

I don't understand how a tv with 50/60hz display can process 24 with no 3:2 pull down or some other processing. Surely it's not possible. My lg tv is currently showing kodi in 24hz and it has 24hz support but has to be using 3:2 to do it. How can 60hz process 24 smoothly as the math doesn't seem possible.

My lg tv (a 50/60hz model) is definitely giving a 24hz output on kodi. The info button shows 50hz for uk tv,60hz for the nexus player and 24hz for kodi. But that results in 3:2 judder. And I still don't understand why all 50hz broadcasts on uk tv or 60hz streams from Netflix , both showing 24hz films or tv shows,have no noticeable judder at all.

Ok thanks. In that case it's very odd that I see no judder at all on nexus player 60hz showing 24p but it's a constant obvious judder when kodi shows 24p on either 24 hz or 60hz. Both use 3:2. I suspect I'll never know why. Would it be of any use asking kodi to speed a file up by 4%?

Hi. Yes I have adjust display refresh rate on normally.
I really wanted your suggestion to work ☺ So I changed the refresh rate to 50 with the tvhz app, checked my tv was showing 50hz, and did all the other things you said. The result is that is consistent with no sudden glitches. But that's mainly because it's consistently bumpy throughout.
In theory following your instructions should mean that 24p sources look the same as a uk 50hz broadcast of 24p but it sadly doesn't. This seems, and I stress seems, to be a fault of kodi as everything else is doing what it should be doing.
I've now turned it back to 60hz with adjust display refresh rate on and the picture is back to being absolutely perfect with the occasional slight glitch that looks like it'll be there until I get a120hz tv. It's maddening to me that I cannot get kodi to do what my 50hz tv broadcasts or 60hz Netflix streams do. Thanks for your help and suggestion though. Much appreciated.

As I said - I have no idea what Android does. I run OpenElec on x86, Raspberry Pi 2 and ODroid C1. When I want to watch 24p on a TV that only supports 50 and 60Hz I always use a fixed 50Hz and a sync playback to display to do the 4% speed-up 2:2 at 50Hz trick as I can't watch 60Hz with 3:2 pulldown for any length of time. (You have no idea how annoying Netflix not doing an easy non-3:2 viewing route is...)
One other question - where are you based? US TVs don't handle 50Hz at all well.

The Nexus Player is a Google product so runs Android. You can't install OpenElec on it AFAIK.
Unless your TV is doing frame-interpolation (i.e. filling in the missing frames) any 24p content (movies, US TV drama etc.) played on Netflix or Amazon and output at 60Hz will have 3:2 pulldown. Some people see this, some people don't. I can't watch it, but other people don't notice it. Be grateful you don't see it.
If you are seeing different artefacts when watching content in Kodi on your Nexus Player then it sounds like you are just suffering from frame drops or skips.
