Thanks Kevin, but that doesn't really answer my question. The remote communicates with the DVR via RF and IR, but that's not my question. I see the green light flash on the DVR when I push a button, that indicates the DVR has received the request from the remote. My question is, does it process this request internally and immediatly? I heard that the request is send down the line to Cox servers, which then send it back to the DVR for processing. For example, if I press pause while watching a recorded program, the green light flashes indicating the DVR has received the request, but then the "pause" request is sent to Cox's servers which then send the actual instructions for carrying out the pause action to the DVR, and the recording gets paused.
