Why are the channels sorted alphabetically?
Fortunately the 2.15 software gets the channels in the correct order (so that BBC 1 is on 1, ITV1 is on 3 etc). You can change it if you want to. It’s called Favourites. You will need to assign the radio channels to favourites though, as by default the Favourites list for Radio is blank. With 2.16/2.17 you may also find that BBC Parliament is put into Radio stations.
