Tvheadend

Hello everyone

I'm running tvheadend in a docker container (binhex-tvheadend if that makes a difference) and it's going well so far. My only criticism is the EIT EPG data is often only partially populated at any given time. As a result, I have tried to get XMLTV working instead.

I have a guide.xml file and have enabled the XMLTV grabber in the config file. Rebooting tvheadend has resulted in a new XMLTV.sock file being created, which from what I've read is a good sign.

But I can't get any further than this. Some pages of documentation suggest that I have an option on the EPG config page to select which grabber to use, but I have no such drop downs, even on expert mode all I get are boxes for Cron schedules.

So I then went to the individual channel configs to try and enter an EPG source, but the dropdowns there are empty and any text I enter is cleared out when I click save.

Any ideas?
