the HDD is named Server HD to help identify it from MacBook HDs that i attach now and then (haven't really needed to in quite a while)
the user is Drobo (i use a Drobo ext hd enclosure to stream data from thus the name)
the file /opt/dvr/Library/LaunchDaemons/org.mythtv.mythbackend.plist does exist.
i can change the HD name or create a new user account if needed, sounds like i wouldn't need to regularly be logged into it so that would be fine
I can't explain why the standard process isn't working for you. The Myth_Stop_Start applescript normally checks for the presence of the plist in /Library/LaunchDaemons/ and creates a link to '/opt/dvr/Library/LaunchDaemons/org.mythtv.mythbackend.plist' if it is not found. You should have to enter your administrator's password (aka the macOS root password) when you double-click Myth_Stop_Start. That password gives the script authority to create the link. And authorizes launchd to start running the backend.
You can try creating the link from the command line:
