I like the way Directv does their hd channels. When any new hd channel is added , it takes the place of the sd version in the lower channel numbers. This way there is no confusion for the subs. With DISH I have to lock out the sd version and the higher versions of the hd channels so the hd lower mapped channel is all I see in my guide. A lot of work if you ask me. DISH should allow you to use the menu to enable the lower mapped channel numbers like DIRECTV does and it would be much easier for everyone.
