I just wanted to add my comments here about IR blasters. I built this one, by Enrique Vidal right from the lirc website http://lirc.org/improved_transmitter.html. I dont use it for channel changes on a satellite receiver, but I use it to control volume and power on my TV.
The 4000uF caps are a bit hard to come by, but the circuit isn't too complicated. I made a mistake of flipping one of the fets on there, and fried it when I first put it together, but else wise I'm really happy with it. It works from about 6 to 8 feet away consistently, even though I keep it much closer to the TV. If anyone is interested to see what it turned out like, I have pictures here with it inside its makeshift casing and mount job near the TV.
