It certainly doesn't - with several providers and mixed DVB-S and DVB-T
channels the idea of each provider wanting to dictate channel numbers is
just not feasible.

Well, if you have only a single provider and/or transmission method, I
can see that you might identify a channel by its number.

You can number your channels in whatever way you want, with the existing
means implemented in VDR - it just doesn't happen automatically. So there's
no need to explain anythign to your wife, if you just sort your channels
the right way ;-)


Are these channel numbers broadcast in a way that's covered in the
DVB SI standard? If so, I see no reason why VDR shouldn't (optionally)
use them when sorting channels. But they sure have no place in channels.conf,
in there I would still use :@nnn lines to set the offsets.
