Comment (by dekarl@…):
Lets see...
Google hints that you might be in Switzerland.
{{{

looks like your DVB card is unable to automatically guess one of the
parameters and you have to manually scan one transport and learn the
others from the network_information_section (NIT).
Looking further it appears that you might be on DVB-C with CableCom and
got a welcome letter with a network_id in it.
The manual network_id setting is not yet hooked up to the GUI, see #7486,
which enables MythTV to find the correct NIT and realize that your signal
follows the DVB SI standard.

Ohh, and the channel.conf parser is known broken at the moment, see #7701
{{{

Looking further it appears that CableCom is only providing CI+ cards, but
no CI cards, which do not work with Linux at all.
Knowing some details on country/provider would help alot as especially
DVB-C providers often need special handling.
