No PVR addons available for Kodi in the repo, you have to use the AUR to install the one(s) you need.
At least it doesn't take long to compile.
Mythtv on the Apple TV blows, no easy commercial skipping, you can only fast forward, not use the markers. No subtitles either.
The only thing better, is auto commercial skipping.
Subtitles don't work, and there's a black border on the top, changing the overscan settings doesn't help.
Can't read lips, so don't know if it's in sync. It seems to be, or pretty damn close.
There's a delay at Kodi exiting, I could see on my monitor, that the Kodi process ended in the terminal, it wasn't gone on the TV yet.
