Stuttering video

What's the best way to reboot the HDHRs?

Between 9 and 10pm.

You can do it from the command line with:

hdhomerun_config FFFFFFFF set /sys/restart self

where FFFFFFFF is your DeviceID.

That does not seem to have worked. I rebooted both HDHRs and then ran a channel scan. Here's the log following the scan...

Do you see stuttering in the official HDHR app?

I've been using Channels so long, I no longer remember how to access HDHR's native utility. Would you please be so kind as to advise?

I don’t believe they have one for Apple TV, but you can download it on an iOS device if you have one. Or Android I think. Here’s the iOS link:

Might I suggest you look at the condition of your drive (especially if it's a hard drive).
I had a similar problem two or three years ago with EyeTV running on a Mac Mini, and the problem was the hard drive going bad so that it would frequently pause a long time trying to sync, or to read a dodgy sector.

Probably the easiest single way to try to resolve this is either

  • move your TV recording to a different hard drive (should get better, but life may still suck if the OS frequently has to hit the dodgy hard drive) and/or

  • download the app DriveDx which looks at the SMART counters on your internal drive and tells you if anything looks worrisome. (It's not free, but is free for the first use I think. And is, IMHO, well worth paying for. Getting it to work for external drives is something of a mission [Apple's fault, not theirs] so you may want to wait till macOS 10.15, where the new Userspace Drivers Framework should make this a whole lot easier.)

I do not see the stuttering in the HDHR app.

The drive seems to be okay. While I'm unable to transfer the file, I did conduct disk health checks and rebooted the drive within QNAP. All seems okay there.

The problem is now worse than ever. Anyone have any suggestions? I'm using a QNAP NAS.

On the Apple TV, make sure "Tuner Sharing: Off" and "Home Streaming Quality: Original" then play a live TV channel and see if it stutters.

On the exact same Apple TV, use the free VLC or InstaTV app and see if the same live TV channel stutters.

It stutters using the VLC app.

That points to a Wi-Fi issue at your Apple TV.

Try running some speed tests on the Apple TV (via speedtest app) or via another device (Frequently Asked Questions)

So here's something interesting. The speed using the method in the FAQ you linked is...

Download: 1.43Mbit/s
Latency: 21.98ms
Jitter: 12.66ms

Using the speed test website on my computer (Wifi, same room as AppleTV), it's significantly higher.

I manually adjusted the DNS settings to match my laptop. We'll see how that goes.

1.4mbps is awful and explains all your issues.

DNS Settings do not affect bandwidth. If you have 2.4ghz and 5ghz Wi-Fi try switching to 5ghz.

Also you should consider hardwiring your devices so you can get 1000mbps.

It seems to have rectified. The speed is now significantly higher. What's interesting, though, is I never experience(d) any issues on the AppleTV outside of Channels. Just fine using Netflix, HBO Go, etc.

The hdhomerun video streams use much more bandwidth than any internet video streaming apps.

There was extensive stuttering, about every 5 seconds on my recordings. I switched to EyeTV so the stuttering stopped. A few days ago, I tried Channels again and the stuttering had stopped. It sounds like a problem on your end. Thanks for fixing it.
