I looked at his logs and I see some similarity but I also see where his is having an issue connecting to his DVR. I don’t see a lost connection to my DVR.
Since switching my audio setting on the ATV4 settings my video/audio has been pretty stable
Did a little more testing tonight. My ATV4K is stable as can be....flawless. I did notice at the very beginning of the video, the video would play first and the audio would delay a split second like it was trying to sync up before playing. I didn't notice this on my ATV4. @tmm1 does that make sense?
Anyways I tested both of my ATV4s, one is wifi, the other one is what I've been talking about above that is wired. I'm seeing slight stutters on both. Not near as bad as the other night after I made that audio change. The ATV4k was snappy and responsive, perfect picture.
But you are changing the audio setting on the ATV itself? That would mean that the ATV is not processing the sound efficiently which makes no sense to me.
I did on the downstairs one. The quick test on the upstairs one that is on wifi, I didn't alter the setting. The interesting thing to me though is seeing that the 4K is buttery smooth while the ATV4s are not.
I’ll also add that I don’t have any stuttering on my 2018 iPad Pro
Can you elaborate on the stuttering? Does the timeline appear? Does the audio also stutter, or just the video?
I have experienced some frame drops on my Non-4K Apple TV, typically with 60fps content. I noticed some dropped frames in your logs too, but it might be a different issue.
Here’s the thread I created on that: Link
I haven’t noticed the issue in a while, but then we don’t use that Apple TV very often.
@scooter_scott What if you set the video quality to less than Original on the client? Do it in steps and see if it clears up at a specific setting.
I moved the client down to 8mbps for in home and the transcoder basically puked. The logs I have are nasty looking.
I also confirmed it’s not my synology. It’s most certainly the appletv 4. I changed my DVR back to my 2018 Mac Mini which has overkill horsepower and the stuttering occurred again. This is a client specific bug in my mind.
I pulled this from my ATV4:

2020-04-30 22:27:19.169 [vd] v: Using software decoding.
Should it be using hardware?
Software decoding is used on Apple TV.
Does this stutter issue happen on OTA channels?
What is the audio setup? Are you using optical? Or HDMI ARC? Airplay?
Yes I’ve seen it on both OTA and TVE.
Audio is thru hdmi arc. Samsung soundbar and Samsung tv. Been running this same setup since I started using channels.
Okay. And just to clarify, the recent diagnostics are with Apple TV audio set to Stereo or not? I'm confused at if and how much that setting helps what you're seeing?
The audio driver is reporting a sudden jump in position which is very strange. This makes the player have to drop video to jump ahead and catch up to where the audio is reported to be.
You can try the Audio Driver: Experimental setting which uses a newer Apple audio API which might have different behavior (and probably different bugs).
ATV4 and ATV 4K don't have a TOSLINK output.
Yes the appletv audio is set to stereo. It helped a little bit but it’s still a pretty significant stutter. Sometimes it goes on for 5-10 seconds. Sometimes just 1 second.
I tried experimental. It was unusable.
Just for s&g's, try setting the audio to Dolby Digital 5.1. Since you have a sound bar connected to the TV, that should work just fine, sound-wise, anyway.
No matter what I set it to the stuttering is still there.
I'm almost inclined to buy an ATV4 now, just to test it on our network.
We'll be buying three ATV4s, eventually, anyway. It's just I don't need another now. The plan was to sell one of the Android TVs and one of the Fire TVs to finance the next ATV purchase.
Excuse me, but I don't recall: Have you tried swapping an ATV4 and ATV 4K to confirm the problem stays with the unit, rather than the installation location?

I have a Synology DS718+, a ASUS TR-AC88U and run channels DVR on the NAS. Works perfectly. Have you enabled bonding of LAN ports 1 & 2 on your router?
Might be worth doing a factory reset on one of the ATV4s. I tried on my dev unit and cannot reproduce the audio issue shown in your logs.
Thank the heavens for that! I was really wrestling with myself over whether or not to buy an ATV4 right now
