I think I’ve identified the crash thanks to @TobiasAmbrosi!! Seems to be related to DNS rebinding protection, which forces the app to play the video through an internal proxy that keeps everything secure.
It seems like the code in that internal proxy is not doing the right thing when dealing with huge amounts of data, increasing memory usage vastly and forcing tvOS to kill the app.
I’ll work on a fix as soon as I can, but if you need a workaround right now, you can temporarily either disable DNS Rebinding Protection in your router if you can, or disable secure connections in your Plex Media Server (in Settings -> Network -> Secure connections -> Disabled).
Let me know if that works, and thanks for your patience!
