I think this is a bad idea. People so far always configured the channels 
manually. While this is certainly not good if required, you should still 
keep the *ability* to do that. There are so many reasons thinkable - 
downloading channel lists from the internet, importing them from VDR for 
migration, adding advertized channels that were not found automatically 
for some reason, broken channel/satellite providers.

It's fine to *additionally* store the information for automatic tuning 
(if the user can choose to override for specific channels).
Fully automatic tuning would be great, if it works well.

Maybe make an extra check, if the channel is really gone, before 
removing it.

I wouldn't treat the DVB network information as authorative, only as a 
hint. IIRC, some of it has been reported as severely broken or lacking. 
So, be careful before altering the tuning information and esp. before 
removing channels. If I have recording schedules on channels that are 
gone, I should be warned and maybe the station should not be removed. 
Adding channels should be fine, as long as I can opt out: I may want 
only a selected few stations and no new ones or I prefer a certain 
channel for a certain station or I don't want a certain station or I 
have no use for stations which are in certain languages only.
