Lower power "off" than turning off = wait 3 hours

The same thing happens to me using a Harmony remote. I cannot completely shut the SMP or Hub off I’ve been using the supplied WD remote instead.  I haven’t been able to configure the Harmony power button to send a signal equal to holding down the WD remote power button.

If I’m not in the same room I just leave the unit on and have the auto shutoff feature shut it down a few hours later for me.
