My channel lineup has two versions for some HD channels. For example, 222 is AMC HD, 1405 is also AMC HD. If I add 222 as a Favorite then, after saving the list, 1405 is also added to the list. If I go back into set up and delete one of them, it deletes both. This is a nuisance when scrolling through the list of favorites (hitting Fav on the remote) since I have to skip all these multiple HD channels. Is it possible to just add one of the two channels to a favorites list?
