Still working on sat
For me its Find the working channel then menu, add service to bouquet, put into sky uk sports bouquet, exit out and go to sports bouquet, the channel should be there as the last entry, highlight it, press menu again, then enable move mode and then just replace it with the non working channel and exit out.
Can you just not replace it with the original, that no longer works. to move when you are in the enable move mode, just go onto the channel and press ok and move with the up and down arrows.
Did you get it sorted mark
