Comment (by Klaas de Waal):

 Until proven wrong by a log file, my best guess is that in the "Without
 tick" case there was a timeout on the NIT so the network_id for Com78
 National (12357) and the logical channel numbers are missing. In the "With
 tick" case the NIT must have been correctly received.

 About the MyGica T230 tuner, I have found that on my system the scans with
 this USB device are usually not as good as scans with PCIe bus tuners.
 With the MyGica there are lots of "AddTSPacket: Out of sync!!!" error
 messages and this can be the reason that sometimes the NIT is not
 received.

 Because the logical channel numbers are in the NIT the "LCN required"
 option effectively discards the result of a transport scan when the NIT is
 not received.
