I have an Apple TV 4K wired up with a gigabit connection to my server.
Some of my 4K videos will always stutter even without subtitles and with basic stereo or DD5.1 audio tracks. Also doesn’t matter if it’s HDR or not.
The only similarity I can find between them is their bitrates can go over 100Mbps.
Is this possibly a limitation of the hardware or the software? Another issue entirely?
