I have a RPi3B+ with the latest version of LibreELEC. I have installed the tvheadend server and client and configured the server via the web UI. I can watch live TV, but that is where it stops working.
I can neither record a program that is currently in progress (though the timeshift works fine) nor schedule a recording. For a recording that is currently in progress, it says "Recording Started" or something like that, in the upper-right dialog in LibreELEC. However, Immediately after this, it says "Recording Completed", and never records anything.
For the scheduled recording, it does this same thing, but instead of happening immediately, it happens right when the scheduled recording starts.
I apologize if this is unclear, or if it is just a stupid mistake I should have figured out by now. If you need more info, please feel free to ask.
Thank you for your time,
P.S. My tuner is one of the HDHomeRun network tuners.
P.P.S I had done this same thing a few months ago, and if I recall correctly, everything worked fine.
