hello, new to libreelec, I felt the need to change my player after my shield tv tube started stuttering with high bitrate mkvs (thought the problem was my nas )
my humble contribution
I was able to see the red sign screen "this device can decode fel", the white font credits and the character from mortal engines on the sample videos, using this gear.

Hope that indeed everything was working. I read that receivers were not part of any test so far, in my case they seem to work fine.
