Thanks Sucmnsee and Dumbguy - when I press the down butoon to bring up the channels they are all listed on screen (filling all the screen), but not by the groups of entertainment etc whereby you would nomally see 6-8 groups i think. So when I tried the move option I was just moving them through the list on screen.
Anyhow, as per #22 BBC1 HD is now showing on 101 for my region and UTV is showing on 103 (which is fine), but strnagley I had to pick London to get it to show like this - whcih is confusing
