The Guide is not well programmed. Basic, common sense functions are missing.

When I select a HD channel as a favorite, the system also automatically selects the non-HD channel as a Favorite too.

I do not want that. The only time I want a non-HD channel as a Favorite is when there is no HD alternative. 

I can select HD Channels only on the Guide, but then all the channels I will never watch show up. 

I need to be able to select ONLY the channels I want as Favorites.
