[mythtv] Is it normal to rerun the same select query every 8 seconds?

it is also possible that you did not add encrypted and radio channels
in the first place. There are option in the channel scanner to omit
them.

yes, http://www.linuxtv.org/wiki/index.php/Dvbsnoop says
"not on Fedora", too :)

The EIT section scan will look something like this:
http://dvbsnoop.sourceforge.net/examples/example-eit.html

each event_information_section will begin with (among others) the
following attributes:

Service_ID: 47 (0x002f)  [=  --> refers to PMS program_number]
...
Transport_stream_ID: 33 (0x0021)
Original_network_ID: 133 (0x0085)  [= BetaTechnik | BetaTechnik]

which should match your database queries (The ONID is called NID in
MythTV for historical reasons)
