[mythtv-users] No signal lock when trying to watch live TV - HDHR DVB-C Telenet (Belgium)

[Klaas de Waal]

Setting /sys/dvbc_modulation to the correct value before starting
mythbackend should be enough. It then should work with the
"...auto..." tuning commands generated by mythtv. I have two of those
DVB-C tuners and for one of them this is enough, but the other needs
an explicit tuning command as described in ticket #13371. Your mileage
may vary....
But you say mythtv-setup does work and this generally means that
mythbackend should also work.
Note that in mythtv v29 the mythbackend needs exclusive access to the
HDHR tuner, so you should not run other applications like the Android
HDHR app at the same time.
