I keep getting conflicting information. My mom in tampa want's to get directv. 2 regular units and my old directivo. will they refuse to install it w/o a phone line? My tivo already is hacked to not make a phone call. Im trying to figure this out so we don't get them out there to just refuse the install. She never want's ppv so that's not an issue. Does anybody have a straight answer? What about best deals? I don't mind having to go through someone local to get it installed.
