The Pi and Pi 2 support ISO for DVDs and 2D Blu-rays with no problems. You can play them over a network connection or from local storage.

What they don't have is support for ISOs of 3D Blu-rays - though it is being worked on I believe. This is because the ISO format for 3D Blu-rays is quite 'clever' and uses some quite interesting UDF functionality that allows for 2D compatibility (effectively different 'files' in the UDF ISO image point to the same data) If you want to play 3D Blu-rays on a Pi you have to rip the ISO to an MVC MKV using MakeMKV or similar.

I don't think any Kodi platform supports 3D ISOs within Kodi - only via external players.

Okay, thanks for setting me straight. I figured I was missing part of the story.
