If the OS Mini+ is configured as satellite you need to reconfigure the tuner to scan terrestrial/cable.
Workarounds:
AutoBouqetsMaker Plugin (available on OpenPLi feeds), scans UK cable, NL cable, UK terrestrial, and NL terrestrial plus most satellite providers too. Channels are made into bouquets with the channels in LCN order. This plugin works with the tuner of the OS Mini+ configured as satellite.
TerrestrialScan Plugin (available from oe-alliance). Scans all European muxes. If there are duplicate copies of any transport stream (i.e. multiple transmitters) it chooses the strongest one. Channels are output the same as a conventional E2 scan (i.e. no bouquets). This plugin works with the tuner of the OS Mini+ configured as satellite.
