As other have noted, Samsung does not provide discrete on/off for their BR players. However, even if they did I think you would have the same problem if there is a disk in the tray. The stupid thing insists on loading the disk before it will respond to a command to stop (try it - just power on with the power button). I always turn the system on with the eject button and remove any disk if I want to access Netflix.

Too bad that the disk people have not gotten the message since their panels have discrete on/off.
