Well powering off is not really an option to all of us, like me. However
we might implement several additional levels of power savings.
How about lowering the voltages used for the LNB. Maybe we can save some
additonal energy back then, even when we watch TV.

I've just gotten an inspiration. Has anybody ever tried if the DVB card
still gets warm when you disconnect the shield? (Mine's currently
defective). If it doesn't, we might actually build our own LNB power
supply. Maybe it could be a lot more efficient than the current one.
