So 4K yay! Or So I thought.
My server is a i5NUC with single gigabit network connection. The files are on a NAS. So even on direct play the server reads from the NAS to the NUC then NUC to the TV... Maxing out at about 50-60Mbps tv only a 100Mbps connection so buffers every few seconds. Run Plex on the NAS I thought because it won't need to transfer both ways on the network. This has better results but still buffers every 10-15 seconds. I have tried 4K HDR H265 and 264 with similar results. just over 1:37 long and 43GB's in size.
How can I resolve this???
