Hmm ! I too am on the Sunshine Coast - I have 7TWO set as 62 and, because iceTV won't allow me to use 7TWO - QLD (long story), I have 7TWO - QLD "disabled".
BUT - when I display the EPG - BOTH have EPG data !!
I was about to launch into replying to your other post about all the SC channel changes, but it seems to have disappeared.
We get both local and Brisbane retransmitted channels from "Bald Knob" . Is that your situation too?
