On a slight tangent: NIT scanning has its own pro's: Many of the Astra 
and hotbird sats have very different customers. These customers use 
different CA systems. Normally when you want to receive encrypted 
streams, you will buy an CI module for 1 provider (= 1 particular 
customer of the satellite). Enabling receiving encrypted streams in myth 
will give you *all* encrypted streams, including most you cannot 
decrypt: different CAS, different EMMs.... This could be solved by doing 
a NIT scan: first check which NITs are present, then present the user 
with a list of NIT (NIT network id, original network id and descriptor) 
and let him select which NIT he wants to have. Only channels within the 
users subscription (or at least from the same broadcaster) will be added 
at that point.

Cheers,
