That's a configuration error. A video source should not contain
channels that the card input it is attached to cannot handle.

Another configuration issue. 'Equivalent' channels on multiple video
sources should have the same callsign so that the scheduler considers
them equal for scheduling purposes. In the case of DVB-S/S2 and using
EIT listings, the 'equivalent' channels on each video source should be
receiving the same data.
