I am not sure I follow. You should just make the settings I wrote, exit Kodi, then make sure your desktop refresh rate is 59 or 60 Hz, then start Kodi and check some 23.976/24.000 movies for framedrops (a few drops at the beginning is normal). Kodi will switch to the correct refresh rate at the beginning of the movie automatically and will restore 60 Hz at the end.

I explained wrong sorry, i have no frame drops, but there's some problems with audio/video sync, somehow frames get dropped for audio to stay in sync when bitstream is on (this gets duped with sync playback to display on), but there's still some minor "24P" judder happening randomly which shouldn't happen compared to the other player (Stereoscopic player which uses coreavc + lav filters).
Edit: "Sync playback to display" also doesn't seem to work that well with MakeMKV rips, everytime i rip a 2D movie with makeMKV audio will sit at 99% while video is jumping around from 95-99%(This is the reverse with BDMV folder structure, Audio fluctuating between 90-99%, video 99%).
Playing BDMV folder without "Sync playback to display" results in craploads of dropped frames for Audio to stay in sync, but none of them are reported as "dropped".

You are trying to set the refreshrate in windows control panel before starting Kodi? Don't do that, it is broken too! It will show that your display is at 24.000 Hz but in the background it will set 23.976 Hz! It's not necessary and will only confuse Kodi's refresh rate switcher. I would really love to talk to the engineer at Microsoft who is responsible for this mess.

I've found that just switching Plex to a full-screen window solved the problem there too for 24.000hz playback. It no longer skips frames.
There's definitely some bug because if I set Plex to full screen (non-window), bearing in mind my desktop is set to 23.976hz, when I start a 24.000hz movie, the screen blanks out like it's TRYING to switch to 24.000hz, but then when the movie starts, Plex info reports it's still running at 23.976, not 24.000 (same thing happens with Kodi 15/16). That's why it's skipping frames, because playing a 24hz movie at 23.976hz is a bad idea as we know. However, if I run a full-screen window in Plex with 24.00hz material, the screen blanks, Plex info reports 24.00hz frame-rate correctly when the movie starts, and there are no skips.
Problem solved - just run a full-screen window in Kodi/Plex. Thank you.
Now the only question is whether there's any downside to a windowed full-screen? I may just leave it this way in future..
PS It's interesting the full-screen window workaround has worked in Plex Home Theater for a long time... I wonder why that is, since Plex is very behind XBMC.

Plex might had this patch implemented earlier. I am not following its progress. Fullscreen window does not really have any drawbacks in Kodi on Windows 8+ since the DX11 upgrade. A bit slower performance theoretically but it really depends on your GPU/skin. I highly doubt you will see any performance penalty with your GPU, especially since you are running your desktop at 23.976 Hz.

I've been running in full-screen window for a long time and have never, ever been able to get synced audio for 24fps movies. Will try with Jarvis and/or the DX11 build linked to last page and see if that solves the problem.
