I have a similar idea that I've carried in my head for some time. The idea is 
to extend the "channel number" by another character, like '.'. That way you can 
store the dvb-s channel as 100.1, the dvb-t as 100.2, and so on. Or if you have 
the same channel in HD and SD, give SD the 100.3.

The channel number 100 would be an alias for one of the 100.x channels, 
ChUp/ChDown will go to 101 or 99 directly. Recordings for channel 100 will also 
pick the first available of them. By hitting a '.' key on the remote, you can 
still enter the sub level, where ChUp/ChDown cycles between 100.x channels, or 
for timers to record from a specific source. Hitting '.' again could return to 
the top level of numbers.

Of course this would require a rewrite of the channel numbering code, probably 
by making the current channel numbers internal only, and having an additional 
UI channel number as string. For the channels.conf syntax, this could be an 
extension to the :@ syntax, where :@. or :@100. or @100.1 starts a group of 
channels. And maybe an empty :@ to end the group without explicitly setting 
:@101 as next number.
