embarasing, but its been so long in years since i have had a cable box, just using internet, not sure i can wrap my head around answering your pertinent question.
currently, i have the typical motorola surf modem for internet access. i had thought the sales rep with cox said i didn't need a cable box with basic cable service, hook up the tv and then scan channels. may be she and i mis-communicated the new cable package and i need that cable box with hdmi out?
