Latest Beta - Tuner Sharing not working

Channels DVR Server
#1

I am not sure how long this has been broken, but I have been using the latest AppleTV Beta with PiP. I tried switching DVR to latest Beta just now, but no change.

It seems like tuner sharing works for TVE. But not for any of my OTA channels:

The channels seem to play on the ATV direct from HDHR. And I do have recordings from the OTA channels, so that must be somehow working... although the log looks like this:

EDIT: THis seems to happen only on the Quatro. My other tuners don't seem to exhibit this issue. I'm going to try a firmware update.

Anything in your HDHR System Log?

The Quatro is not tuning it for the DVR. For some reason. But it tunes fine for the ATV.

System Log looks like this:

Updating firmware on the HDHR is risky. SD could be messing with the tuning alorithms. I have all channels from two cities perfect and wish I didn't have to mess with it.

Ugh. After a lot of messing around with all sorts of things, I have managed to resolve this issue with the Quatro.

Any idea what resolved the issue?

Well, I first eventually noticed that it was only the Quatro that wasn't working right. Channels DVR couldn't tune it, but my ATVs running Channels could. I reluctantly tried updating the firmware. And Channels DVR to latest beta. Channels got real laggy on the latest beta, so I rolled back to a few older versions, trying about 6 different older versions to see if any resolved the tuning issue. They didn't. And I eventually moved back to the last official release: 2021.02.04.1931. But it still didn't fix the issue. In fact, now no apps could tune any channels on the Quatro. The ATVs stopped working with it too. It was as if the HDHomeRun firmware update broke it more. I could verify the lineup using http://<device ip>/lineup.xml. And I could tune it by using SignalGH or by setting a frequency using hdhomerun_config from the shell. And it would report that it was tuned with 100% signal quality on most stations. But if I tried to tune it with Channels it would fail. It also didn't work using HDHomeRun app or VLC using the http streaming address.

I tried doing a scan on tuner0 using hdhomerun_config. Which didn't resolve the issue. And then I did a rescan using Channels on the ATV. And then things suddenly started tuning again.

So it was a lot of troubleshooting for something that a simple rescan from Channels may have fixed. I've been using Channels DVR since its inception. This is the first time I have had that happen. The channel frequencies didn't change. I was still able to tune them using my other HDHomeRuns. It was something glitched with the HDHomeRun Quatro, though, not with Channels.
