There are a number of HD channels coming on line and they are going to be mirrors of existing SD channels. How should that work? I think I read that the HD channels might be on the same channels as the SD ones, like RSNs and locals are now. That makes sense. But how could you quickly switch from one to the other? Do you think it would make sense if the SD ones were redesignated as -0, example 229-0 for SD where 229 is HD? Or if you input the number as 229, you get HD, as 0229 you get SD? Personally I like that one. I don't know if it would work with the current logic but it might. What do you all think?
