The pid file exists and has correct contents.

Very interesting, we have:

[Unit]
Description=MythTV backend service
After=network.target mysqld.service
# uncomment the following line if you will be using the mythweb plugin.
#Wants=httpd.service

[Service]
EnvironmentFile=/etc/sysconfig/mythbackend
ExecStart=/usr/bin/mythbackend --daemon --user mythtv --logpath
/var/log/mythtv/ --pidfile /var/run/mythbackend.pid --syslog none
PIDFile=/var/run/mythbackend.pid
Type=forking

[Install]
WantedBy=multi-user.target

So that all looks OK w.r.t. your description...
