Or move One HD on to 1/101/001 and during the regional opts point people towards the SD channel - instead of the other way round as of now.
Ofcom/DCMS don't consider the HD versions of any PSB channels, to be PSB, so they are not permitted 'high' up on EPGs
on HD receivers, unless they carry exactly the same content 24/7 as the SD version.
That's why BBC 1 HD nations are on Freesat (and Sky?) Ch 101, but not BBC 1 HD in England.
That said, plenty of Freeview TVs allow you to edit and move EPG allocations around to whatever you wish.
I've had the main 4 HD channels on EPG 1-4 for five years (and of course C5 HD on 5 too)
