It is funny how you constantly jump from Pi to Q5 and back

Both are excellent; I use them interchangeably. And, Pi2 gets better with every Kodi 16 build; they're more solid than beta/final firmwares from other manufacturers.

I would imagine just about any Windows laptop or pc with an O/S 7,8, or 10 is Kodi compliant.
What would matter is what sort of CPU and GPU is in it.

Need something that can pass HD audio and do perfect 23.976, both under Windows.
