In the old gtk interface there was a GUI dialog/tab for configuring the 
DVB-S/C/T devices. It used the lowlevel information like freq, lnb's 
etc. However that is not so user friendly.

The dvb drivers come with a utility that scans the satellite and writes 
this info to a file. I don't remember if it was ever implemented in vlc 
to read this file and let the GUI tune channels by choosing a name.

Changing DVB-S/C/T channels by name is the way to go for the GUI. 
However it means more work on the lowerside to provide a user 
recognizable channel.
