I'm using my RPi 3 B+ with LibreELEC Kodi 18, and I'm outputting via Composite cable to my NTSC CRT TV set. 📺
The image quality is perfect, and I'm happy with everything except one thing.
24fps content has judder, and I seem to be unable to turn on 3:2 pulldown as a result. 
Could anyone help me enable 3:2 pulldown on my setup?
