Well, I finally got around to doing the test (with my new Kill-A-Watt).
It took all of 2 minutes to see--and to be sure I kept the receiver
powered off and hooked to the Kill-A-Watt for a while (no change over
time--it doesn't "eventually" power off completely). I'm satisfied that
my DISH network receivers officially take /exactly/* the same amount of
power whether turned on or turned off. DirecTV is probably the same.
My DISH 4922 receiver takes 16W--on or off. My DISH 311 takes 11W--on
or off. Turning off the receiver (without unplugging the receiver) is
useless. Unplugging the receiver is too much effort.
I've heard that the PVR-style DISH/DirecTV receivers take ~40W (on or
off), so if you have a DISH DVR/DirecTiVo/DirecTV DVR and want to save
power on your receivers, "downgrading" to a plain old receiver should
help. Otherwise, going to cable/antenna is your only "easy" option, or
rigging up some kind of switch between the wall socket and the receiver
is an "is it really worth the time" option.
*OK, so, technically without the "power" LED glowing and any other
less-visible changes caused by powering off, there may be a difference,
but any difference is below the resolution available on the Kill-A-Watt
(seems to be a 1W resolution).
