Channels freezing

Channels Apple TV Troubleshooting
#1

Playing on my Apple TV that’s on wireless I keep getting complete freezes and I would need to completely close the app and reopen it. I also tried rebooting the Apple TV but that didn’t do anything either, so I checked the logs. Here’s what it showed:

Sounds like a bad connection between the DVR and Apple TV. Turning off the tuner sharing option should fix it.

I thought It could be connect based too (but didn’t think of Tuner Sharing), so I checked a Speedtest on the Apple TV and I was getting 250Mbps+ to the internet. I also ran iperf3 from the server to a computer connected to the same AP that the Apple TV was connected to and was getting 940Mbps.

I also copied everything over to my Synology and ran ChannelsDVR from there, and it was the same problem, and that has 4 NICs with link aggregation and I don’t have problems doing anything ever from it. I popped up my iPad and it froze on that channel too, but the Apple TV on a different HD channel played just fine without freezes. I tried to use the HDHomeRun iOS app but that was just giving a black screen so yay…

It could have just been the stream from the cable company was bad and Channels didn’t know how to deal with it? I didn’t think of that until after I left for lunch, but if I see it again I’ll download a copy of the stream and send it to you.

I dealt with this exact issue a few months ago. I have two hdhomerun connects and it was only occurring on one of the connects. If I would reboot the hdhomerun it would work better for a while but then after a few hours issue would start again. It would happen with tuner sharing on and off. I change my tuner priority and ignored it for a week or so and then I upgraded to hdhomerun beta2 firmware and have not seen the issue since.
So I have no idea if it was firmware related or what. But it wasn’t a connection problem bc everything in my house is hardwired.
