All of the sudden my Premieres only have SD Menu System. Both a XL 4 in the Den and a original premiere up stairs. If I go to the settings>display hd menu is not a option. I have also tried THUMBS DOWN>THUMBS UP>PLAY>PLAY The HD Menu system is gone. I have the upgraded fios internet package. Netflix streaming works fine. The boxes are hard wired (each of them coming off a network switch) Anyone have any ideas? I called tivo and they recommended me ordering a roamio box I just want to get my existing equipment working like it was yesterday.
