Does AT&T TV offer the HD Extra Pack like Direct TV does(MGM, Smithsonian, Sony, Hallmark Movies and Mysteries channels) as an add-on package? And the HBO, Cinemax, Starz, Showtime premium packages contain all the channels like the Direct TV premium packages?
Only options are premium channels like HBO, Showtime, etc. No you do not get all the channels but you access to the apps.
