The only way that I’m able to get high bitrate, HDR, 4K files to play is using one of the DLNA clients to the Plex server. If I play a file with DTS from the real plex client on my Xbox, everything works well, except after a few minutes it gets stuck buffering.
On the other hand, if I use a DLNA client, like the “TV and Movies” app, find my Plex server, it plays smoothly throughout, except there is no audio, because Xbox does not support DTS, and doesn’t seem to pass it through to my receiver.
My assumption is that Plex server knows to transcode DTS for the Plex client, which is why it works in the Plex app, but doesn’t know to do that for the DLNA client. Is there a way to make it do this, so playing via DLNA will work even with unsupported DTS audio like the app does?
