Every single time I run my M3u playlist on channels, I always get signal drops or tuner quit, etc. I also get stutters every once in awhile. How do I know that this is a channels issue and not my IPTV signal? I run the same signal on a different app and keep it for hours and no problems there. The server is running on an intel mac mini 8gb ram so shouldnt be having these kind of issues. Its hard to watch live TV using channelsDVR for fear of constantly getting signal interruptions.
just submitted diagnostic logs
New issue this morning... MPEG TS "streaming to the tuner failed".
What client?
Apple Tv 4K. Current Gen
Strange. Have you done a speed test back to the server?
Its on all the clients. Web, apple tv, shield. Randomly last night it just stopped taking in the MPEG-TS signal.
I've seen this with the Shield for sure. Connection Reset. Not the ATV. Have you ruled out your network.
Yeah, this is a specific thing that started last night with it not accepting the MPEG TS signal. Server is hardwired and so is the client.
What is the source?
let me also state that as of last night, all my personal sections are no longer generating any info. All the playlists I had organized are gone even though they still remain in my channels collections. Something weird happened.
What is feeding your DVR? Like what is the source?
I'm just curious like are you using ADBTuner, HDHomerun, TVE?
m3u playlist. works fine as an mpeg-TS signal on other apps.
That doesn't help lol. Maybe your upstream (potentially pirate) provider is having issues. 
When you added the custom source to the Channels DVR, did you use the Mpeg-ts under Stream Source and how many channels does the M3U have with it?
I think, have read, streams that are pure .ts often lose connection.
I have read using Threadfin or xTeVe can smooth them out but have not tried,
is that possible in CHDVR?
Yes, of course. As I said, everything was working fine and then suddenly the MPEG-TS signal doesnt get accepted by channels. I run the the same playlist on other external players and they have zero issues with the mpeg TS signal. If I convert to HLS, the quality is pretty bad but then channels does take it. Makes no sense why it stopped working all of a sudden.
"The media could not be loaded, either because the server or network failed or because the format is not supported. " from the web player.
I get that as well with a local MPEG-TS stream from the web player.
If you search the forum for that error, you will see posts going back to 2017.
It's a generic error message with many root causes.
Try using the DVR web UI player in a non-chromium browser, like Firefox or Safari.
