I’m trying to run 4K content through my LAN to Plex on my Xbox from my Synology NAS.
The issue is that some of the content streams just fine and some of the content buffers heavily so much so it’s unwatchable.
I’m confused why some works and some doesn’t so I played each one individually and listed what Plex said it was playing at the time in the dashboard to get as much info as possible in the hope that someone might be able to spot the problem?
Here’s the list:

Also when playing from my laptop on a Wi-Fi through the web browser when logged into Plex they play fine. I noted that when viewing “Content 13” through Plex on the Xbox it transcodes it to 1080P as follows which is probably causing the issue with CPU usage:
Video: 4K (H.264 Constrained Baseline) > 1080P (H264)—Transcode
However, when I played it through the plex web browser server it plays fine and in 4K as it should be:
4K (H.264 Constrained Baseline) > Direct Stream
I have also tried Plex on the TV app as well as the Xbox with the same result. My setup is as follows:
NAS: Synology DS1815+ (upgraded to 8GB RAM)
TV: Samsung QE75Q9FN
Soundbar: Yamaha YSP-5600
Streamer: Plex on Xbox One S
HDMI Splitter: HDFury Maestro
LAN: 1Gbps
The HDMI splitter is to split the video and audio from each input and then sends the video direct to the TV and audio directly to the soundbar. This bypasses the need for ARC so I can get true Dolby Atmos. I’m 99.9% sure this isn’t the issue though and this just passes the signal through and everything is either processed either on the NAS or Xbox and the network throughput should be more than ample I would have thought?
Thanks for your time reading and help.
