So I had COX (orange county) tech come out to install my 2 cable cards on my S3. Only issue was not getting the HD tier (ESPN, DISC) this was only because the guy at the office have them on the wrong downstream. Second level support fixed it. Both cards worked right out the gate. No issues He was out less then an hour. My only question is I still don't understand on the sport packages like center ice. If I pay for in advance why does it need 2-way comm for it?? How is it differant then say HBO. I'm not interacting with the box like PPV pulling menus and ordering movies. Also if I order a movie online why cant they pipe it to my card #??
