I've got a box in my room, but it is the regular box, not a recorder box. We have one in our family room with a DVR. However, the programmes recoreded on that can only be viewed on that TV.

Cablevision uses cards - like credit cards - to descramble the channels. These go in a slot on the box. Right now, all they do is descramble, but eventually, you will be able to use them to (somehow) view the DVR programming on all boxed TVs.
