I have the E+ Fox ESPN custom channels container installed, any recordings in progress will not stop if you press manage and stop. They just continue.
Can delete them after they finish.
Are you sure it's not just taking Channels DVR awhile to respond?
I've noticed with custom m3u channels it can take over a minute sometimes.
You can verify the command was sent to Channels DVR to stop the recording by enabling HTTP Logging (Record all HTTP requests to the DVR log) in the DVR web UI Experimental settings.
When you select to stop or cancel an in progress recording, you should see this in the DVR log where it's DELETEing the running job.
[HTTP] | 200 | 15.470811ms | 192.168.1.8 | DELETE "/dvr/jobs/1714187768-ch9198"
Then shortly after that it cancels the job which stops the recording.

Yeah I think that's it, thanks for the explanation.
