I am having the same ATV 4K stuttering problem reported by others. Internet connection through Comcast is fast but ATV goes blank for a second every couple of minutes particularly when streaming content from Apple and from Hulu. But I've seen it on all of the streaming services during the past several months. This never happens when streaming directly on Comcast services. Disconnections and resets do not help.

This usually indicates a poor internet connection where the Apple TV is located. Speed of your connection is one thing, however if the Apple TV is located in a area where the Wi-Fi signal strength is not strong then you may have problem with your network which may require a network upgrade.

The download speed is 540MB. I tried these steps above but the buffering problem continues.
Are you using any third party VPN apps and or additional network security over and above what your router's default settings are?
