Hi everyone. My first post here but I've had my replaytv (5040) for a couple years. Anyway, I had a question concerning my cable box. I am in NJ, Cablevision, and they made me get a new digital cable box (Scientific Atlanta, model Explorer 4200) today. So, when I hooked it up, i can't get the ir blaster to work on any of the codes suggested. I was wondering if anyone had this cable box and had success getting the ir blaster to work. Any help would be appreciated. Thanks.
