Hi guys.
I'm sorry but I still can see choppy video/frames skipping on Nvidia Shield TV.
Nvidia Shield TV is setted to 3840 × 2160 pixel @ 60 Hz.
I have tested both kodi-20180117-c8e69045-master-arm64-v8a and kodi-20180116-a42a8fa4-master-arm64-v8a.
I still can see choppy video/frames skipping with 23.976 fps videos, the same videos played with others player on the same Nvidia Shield TV are smoothly. On Kodi I have 'Adjust display refresh rate' setted to Off (video output is always 3840 × 2160 pixel @ 60 Hz for all videos resolution / fps).
In order to see that video/frames skipping is important to DISABLE any "Motion Interpolation" on the TV otherwhise the tests make no sense beacuse the TV will go to "insert" additional frames "in the middle" of the original frames.
Motion Interpolation (or Motion-compensated Frame Interpolation or Frame Interpolation) is called in various ways according to the brands (commercial name): Intelligent Frame Creation (IFC) for Panasonic; MotionFlow for Sony; TruMotion / MCI (Motion Clarity Index) for LG; Clear Motion Rate (CMR) for Samsung and so on... More info see:

Please is it possible to better investigate that issue?
More, can you try to test again videos/movies with 23.976 fps and make sure to have the Motion Interpolation feature disabled on your TV for that tests?
Thanks for your collaborations.
