Ok so we have a Samsung smart tv and I have plex installed on it but for some reason it doesn't like playing anything.

There are so e things that will play but I would say 90% just won't play and I get an error.
i have googled this and it's quite common but can't find a solution.

Does anyone one else have a Samsung smart tv with plex installed?

samsung UE50MU6100
running latest os and latest plex build.

I have tried forcing the server to transcode by unticking the boxes allow direct play and direct stream but still no go.
