• satellite-sync shows some channels as end-of-service, e.g.,

        14:44:34 Retrieving / parsing channel data
        14:45:12    p = previously imported/synced channel
        14:45:12    . = channel not yet imported/synced
        14:45:12    e = channel no longer supported (end-of-service)
        14:45:12    base-channels:
