Scan dvb-c with wintv dualhd i get different network ids

Hi

I live in denmark and use yousee cable dvb-c
I must use id 100 but very often that option is not shown
When i can choose id 100 only about 50 channels are found but it should be about 200
I also have an octopusnet and that device finds 204 channels using the same connection.

What is happening ?

Best regards
