I noticed tonight than my recorded show was stuttering quite a bit. I opened the stats and saw the cache was low. Pause tv, cache fills up, play it drains. Rinse repeat. Troubleshooting leads to the combination of AppleTV 4K + AirPods Pro somehow straining the AppleTV.
AppleTV is on 5g WiFi, full signal. Show plays fine with full cache without AirPods, as well as on iPhone with and without the AirPods. So somehow the AppleTV is being stressed. As soon as I disconnect the AirPods the cache begins filling again. AppleTV full power cycle completed to no effect.
