The users are right, this is a issue/a not elaborated feature. I had a LG 42LM620S (2012 model, with NetCast) and this TV merges all the channels, and you have the same problem with DVB-T TV and Radio. If I press "3" the TV list (before change the channel) shows the channel 3 from DVB-T tv/radio and DVB-S tv/radio, giving priority to the actual system (if you are in a DVB-S channel it first shows the DVB-S 3 channel) ¿What happens if you are with channel + -? It shows first all the DVB-T TV, then DVB-T radio, DVB-S TV and DVB-S Radio. If you enter in the channel list it has 4 lists So no, merge the channels is not a problem because LG 2012 series do it, and do it very well.
