[17.1] Play Using Advanced Settings?

Hello everyone,

I’ve been using Kodi/XBMC since version 12. It’s always been a great go to program for medias. It got lots of improvements, many of which I like.
Krypton being the best update there is, running nightly, downloaded yesterday, I’ve started using “Play Using” option in the context menu
because I recently bought a samsung smart tv. Which has been working great together. But I work, and I’m not alone, that other person has trouble doing the “complex stuff as he says” so I wanted to choose the default player in the “Play Using…” option in the context menu. I’ve tried looking at the available options in the Advanced Settings and I’ve tried setting it to extplayer or even TV instead of the default “default” option. Nothing seemed to work.
Does anyone know how to acheive this? I am running Krypton Nightly on a 64bit Android 6.0.1. If you need further info from me, ask away. I can’t seem to find more details to explain my problem.
