I can't record from the Video Output connector in the back of the LivingStation. Why?

• To record from this connector, the input signal (cable box or other set-top box) must be composite (RCA-type connector), not component (3 connectors: red, green, blue) or S-Video, and the program received from the Video Input source must be displayed on the TV.
  
  For example, to record a broadcast from a cable box (or set-top box) connected to Video Input 1, the signal must be composite and the program received from Video Input 1 must be displayed on the TV.
