Intermittent video stuttering

I'm not 100% convinced if it is tvOS 14.2 or Channels (non-DVR) with my HDHomeRun Dual.

I have seen recently intermittent video stuttering show up while watching TV. It shows up for a few seconds and then goes away for a few other seconds.

When I look at the built-in stats (thank you for that!), I see that there are dropped frames on the output portion of the process, which leads me to think its not network related

All my devices are wired in over Ethernet, in segregated VLAN. It wasn't a situation that occurred a couple of weeks ago with the same network configuration, and it works fine on the macOS HDHomeRun application.

I've submitted diagnostics to help the Dev team, and here's a video capture of what I see:

If anyone got any ideas, I'm willing to try them out, because it is getting somewhat annoying.

I’m getting the same right now. Never had an issue since I had channels but get a short stutter ever say 15 minutes, it’s very strange.

Restarted Apple TV, server, and hdhomerun. Still happens every so often no matter what.

It's definitely tvOS 14 as it happens to all 3 of my Apple TV's. In order to fix it you have to perform the following steps.

Disconnect wired Ethernet.
Connect via WiFi.
Connect via Ethernet

It should then be stutter free... but this is temporary as a few days or weeks later it starts to happen again.

Same issue with me as well. I'm running the Pi4 version of Channels through my ATV4K and am seeing the stuttering. This is not prevalent when I use my Chrome Cast for Google TV. I decided to run the beta of TVOS 14.4 and there was no change. Will try @sumolx temporary fix as the stuttering issue drive me crazy.

Are people still experiencing this stuttering issue with iOS 14?

I've been experiencing a very similar stutting issue for several weeks now and am trying to work out if this is the same problem.

I have been having a similar issue. Do you show any dropped frames under options - show stats?
