Hi, does anyone know if I need to buy my own hdmi cables for an install of HD receivers with DTV tomorrow? I called & the DTV rep said, they charge extra? How much should they cost? I read somewhere they come with the receiver. Should I go out & buy my own or should I wait & see? The install is tomorrow between 12-4pm. I just don't want to be over charged for HDMI cables...any anwers greatly appreciated, Thanks
