In the log output the following message appears: {{{ 2019-04-17 21:12:42.500642 E CardUtil[1]: No delivery system selected for capturecard 1 }}} This typically happens when mythtv-setup is run with a v30 database; for DVB cards field capturecard/inputname is then set to ""DVBInput"" which is not a delivery system such as ""DVB-T2"". This problem is avoided by selecting first a delivery system, with ""2. Capture Cards"" / / ""Delivery system"". However, this is not obvious for even the experts, let alone the casual users. The way forward is to implement the following for DVB cards: - if there is no valid delivery system then - get the current delivery system from the device - if that is DVB-T and DVB-T2 is supported then change to DVB-T2 - if that is DVB-S and DVB-S2 is supported then change to DVB-S2 - update the database with the new delivery system N.B. In mythbackend it is already done like this, but without modifying the database. This allows a mythbackend compiled from master to run with a v30 database."
