Oh, sorry, I was talking about the traditional TV that comes through the old standard antenna cable. In those, the TV itself lets you do it, but I realize that it may not be possible in paid TV services. I wonder why they don't themselves move the HD channels forward, though... I suppose by now, an overwhelming majority of TVs have HD.
I don't understand why those TV services don't have channel translation. Where the HD boxes default to the HD channels and the SD boxes default to the SD channels.
Your television probably lets you remap it, in the settings near retune.
