Since a few weeks I have issues with playback of HEVC 4k movies. The movie keeps buffering. I’ve tried a speedtest, the same file i used for the playback is 950 mbps. My “plex server” is better than the previous, i5-4590 and 16gb ram. Normal 1080p movies are no issue. Running tvOS on 13.3. Infuse 6.3.2. Can anyone help me with this issue?
