Can't find "Look for remote players"

If you can't see that option, please check your settings level to be "expert". Otherwise that option is not visible. 

thx DaVu

As "Expert" i could set "Look for remote players" but yet no "Play with" to choose from context when right clicking the mp4-file.
I'm very poor beginner to Kodi and remember i don't want to stream a video from inside Kodi but the Linux desktop itself to explain somebody how to do some work.

thx again and cheers
