I just set up an a trial DVR account - no noticeable change in the performance with the Beta app.
Can you submit diagnostics from the beta app
just submitted diagnostics. HDHR 10531e46
Does changing Surround Sound in the app to Off make any difference?
What about changing Audio Driver to Experimental
Just submitted another log with both flags as you indicated (Surround off, Audio Experimental) .
What is interesting is that the first time I flipped them, the issues stopped. Then i tried to narrow them down to which flag might be causing it and now doesn't matter what option combination I choose between those two, the stuttering is there.
BTW, here is the speed test on the device.
Your logs show frame dropping which is unexpected. I tried your samples on my ATV4 and didn't see the issue. I will need to pick up another ATV4K for my office to test on there.
I just tried on my living room ATV4K and I'm not seeing the same framedrop issue in the logs that shows up on your device.
Can you try updating your ATV4K to tvOS 13 if you haven't done so already?
