man systemctl and search for revert for detail.

sudo systemctl revert mythtv-backend.service

That will remove anything in /etc/systemd/system for that service,
leaving the one in /lib/systemd/system. Personally, I'd keep a
copy of the output of: systemctl cat mythtv-backend.service in a safe
place before doing the above.

Implies that you found something unexpected in the path to the old disk's HOME.
