Tuner conflict when changing channels quickly

So I recently upgraded from my old AppleTV HD to a new 4k, experience has been amazing, Channels runs so smooth and fast now One thing I am noticing is when changing channels quickly through quick guide or last channel, I am getting a tuner conflict message that is resolved with another press of the play button. In this case I only have one tuner available for watching live since I am recording something with the other tuner.

I notice this only happens when I have tuner sharing set to 'On'. If I turn tuner sharing off I am able to switch between channels with no issue. Of course the issue is not present when I have two tuners available as it just switches to the other tuner when masking a quick channel change.

Has anyone else seen something similar? It almost seems like things are working so much faster now with the new Apple TV, everything in the system over wired ethernet, etc., that the channel change request is happening faster than the HDHomerun has released the tuner, but if this was the case, not sure why it would work with tuner sharing off but not with tuner sharing on. Any ideas?

I submitted logs from the AppleTV at around 7:15pm MST for both the case when tuner sharing is off and on.

My setup is latest pre-release server running on Ubuntu PC over wired GbE, latest AppleTV 4K over wired GbE, HDhomerun HDHR4-2US w/ latest firmware from 7/2023.

With your AppleTV set to tuner sharing off, it directly accesses your HDHR tuner, bypassing the Channels Server.

With your AppleTV set to tuner sharing on, it connects to your Channels Server which in turn connects to your HDHR tuner. Channels Server buffers the HDHR tuner stream and will take longer to close/disconnect the stream compared to when your client accesses the tuner directly.

See this post for Direct vs. Stream behavior.

Thanks for the quick reply! I have no issue with a longer channel change time, and would prefer tuner sharing on, but when its on, my channels changes always report a conflict which require me to press play again. So it seems like there is something going on with my server then? Maybe a question for the Channels devs then if there is anything in my logs that indicate what the issue could be?

Please try the latest pre-release and let us know if it improves the situation.

Thanks Eric. Just tried and I am still seeing the 'All Tuners in Use' message. I just submitted logs from both my AppleTV and my server.

Is this specifically for HDHR or does this affect m3u.

My ah4c source doesn’t play nice with channel switching, particularly with channel up/down or numerical input, unless I change from direct play to stream.

@tree2369 I would have to see diagnostics from after this happens to know.

Please try this next pre-release:

Yep, that one seems to have resolved the issue. Thanks again Eric for all the help here.
