Hi @lazylegs. Can you confirm this is what you've been doing? Access the channel list by pressing ‘CH List’ on the standard remote or by pressing and holding the ‘Guide’ button on the Smart Remote. Press ‘Right’ and ‘up’ to select ‘Edit Channels’, then tick ‘All Channels’, and move across to ‘Delete’. Once the channels have been deleted, press the source button again, and select your desired source.
