Why do you want to turn it off? I seem to recall reading somewhere that most STBs draw the same power when on as when off, 
perhaps a fraction of a watt less, but essentially the same.

The cable companies want to be able to address the box whether you have it on or not, for one of their innumerable channel 
lineup changes or to make other "upgrades".

I'm not sure if this is true of satellite receivers or not.

You might want to look into whether it makes a difference in your case or not, it might not be worth the effort.

I would assume you could send the "on" or "off" code using your channel change script. You might have to put a delay after 
sending the "on" code before sending the channel data, to allow it to boot up.

My DISH VIP722 takes the better part of a minute to boot up, which is why I've not looked into turning it off.
