I'm having some issues on my ATV 4K, it's stuttering whilst watching live TV.
It's hardwired into the same switch as the HD Homerun and the DVR NAS. I have another Apple TV Gen 4 but not 4K which is wireless in another room and that is working fine.
Any ideas / and information you want me to dig out of some logs or anything? I should also add that the 4K TV has automatically updated to the new beta (which was an accident...) so I guess there is a good chance that is the issue?
EDIT - I am also getting this with recordings on the wired AppleTV 4K, again the wireless AppleTV is fine.
