Your "protected contend" is using QAM encrypted. So what our STB do is decrypt the signal (removing QAM) then pass the video via analog component cables or even better a digital DVI or HDMI connection. Over that line the video will not be encrypted because there are many TV's there that are not HDCP capable. So we can put any device between there and record. Just like we do when recording analog video over RCA composite cables. The advantage of a HDMI recorder is the video never is converted to analog so the picture will be just as good.
Hope this makes sense.
