So in reality a non-starter for Kodi use outside North America and other 60Hz territories where 3:2 is tolerated for 24p?

Actually, there has been internal talks about handling pulldown better, by inserting "merged" frames.
I'm sure @fritsch will pull that out of his sleeve one day

Eek - that's one step away from the devil's work that is "Motion Flow" or "Natural Motion" (interpolating frames is usually horrible unless you have very high quality motion tracking using Phase Correlation or similar) ffmpeg (or at least ffmbc) has a frame rate converter based on the work done on 50/60 conversion by the BBC for their 80s converters (before vector tracking became standard and when 4-field/4-line blending was the norm) I think it was added around the same time as Weston 3-field deinterlacing (also BBC work that is now out of patent life and has been folded into ffmbc)

(Though I do accept that if you can't alter your render rate then it may improve things. I watch 24/23.976Hz stuff with speed-up 2:2 at 50Hz rather than suffer 3:2 at 60Hz on non-24p-friendly displays)
