Jan, before you go to the extra effort, make sure the STBs actually pull
less power when "powered off". The reason I say this is that most STBs
pull the same amount of power once they are plugged in whether or not the
power light is on. The power button in my experience only disables the
outputs (like component, HDMI, DVI, etc). The STB still pulls 20-30W of
power meaning your effort to power off when idle might be wasted.
