You may need to add the "-v record" option on the mythbackend command
line.  In Ubuntu, you do this by creating a
/etc/mythtv/additional.args file:

root at mypvr:~# cat /etc/mythtv/additional.args
ADDITIONAL_ARGS=-v record,dvbcam

This file is read by systemd in the
/lib/systemd/system/mythtv-backend.service file:

root at mypvr:~# cat /lib/systemd/system/mythtv-backend.service
[Unit]
Description=MythTV Backend
Documentation=https://www.mythtv.org/wiki/Mythbackend
After=mysql.service network.target

[Service]
User=mythtv
EnvironmentFile=-/etc/mythtv/additional.args
ExecStart=/usr/bin/mythbackend --quiet --syslog local7
$ADDITIONAL_ARGS
StartLimitBurst=10
StartLimitInterval=10m
Restart=on-failure
RestartSec=1

[Install]
WantedBy=multi-user.target

Note that my email client wraps long lines - the $ADDITIONAL_ARGS line
is actually on the end of the previous line.

Not all systemd setups do this, so it depends on your distro - you may
need to add the -v record directly on the mythbackend command line.

I always have -v record as you never know when you may need to
diagnose a bad recording.

Even if the log does not show the tuner used, the I key twice on the
recording should show the tuner.
