As for the google searches saying Apple 4k TV does not support MKV unless you 1) convert to MP4, 2) stream from a Mac, or 3) use a player that supports MKV.

While I can play MKV files from Windows, my Synology server doesn't find an app that can and the ARM processor in the server can't convert. I believe the Synology server error is that while I'm connected to the server from my Window's box, I'm actually running off the server, not my Windows box. Now that I see I can, I think I can better understand what was confusing me from before.

Combine that with the Synology error I received above and confusion from Google searches saying MKV files would need to be converted to play on Apple TV, all led me to believe it was a lost cause. When I tried to play them, they actually played fine.Īll I can think is that back in the Spring when I moved from DS Video to Plex and from a Fire 4K Stick to an Apple 4k TV and worked my way through configuring everything, that there was a time I couldn't play MKV files. When trying to play them directly from the Synology server using my computer, I received the Plex Error 'This server is not powerful enough to convert video.' When I went to the HT and checked the Plex settings, they were as Greg said they should be. So, I converted some MPG files into MKV containers and loaded them on the Synology server.
