Just a quick note to say thanks to Memphiz for doing this, and thanks to others for posting guides. I followed the guide here :
http://www.idownloadblog.com/2015/12/24/...pple-tv-4/ and it worked first time.
Very impressed. For me the main reason to do this was to get the SVT Play add-on to work - which allows Kodi access to the SVT Play TV Catch-up service (and won't work in MrMC because it doesn't, understandably, support Python plugins). There is a very good tvOS native app for SVT Play on the ATV4, but unlike the Kodi add-on, it doesn't offer the live streams for the main SVT channels, but the Kodi add-on does.
Few observations and hints :
1. The Kodi iOS remote apps works brilliantly with Kodi on ATV4 (as you'd hope - but it's great that it does)
2. If you are watching European (not sure about US) interlaced content (such as DVD ISOs) then you need to switch to Bob-Inverted as your deinterlacing preference (otherwise you get reverse field dominance and horrible jerkiness as fields are deinterlaced to frames in the wrong order)
3. I have a 16-235 amp and TV set-up, and it appears, to me, that I have set-up (i.e. grey) black levels (as if 16-235->0-255 conversion is being done once too often in Kodi and/or tvOS)
4. Dolby bitstreaming is working.
5. 720/50p off-air TV recordings (peaking at around 13Mbs) are working well. Bit of buffering to begin with - but sold when they start playing.
Impressive.
