Dishnetwork Finally made Discrete codes available on their recievers. Make sure you have the latest software:

There is much more info on the 'Discrete Hunter' forum, but I don't know how to create a link over to it.
Also, from what I read there, it doesn't sound like there is a discrete power code for the 721 yet.
I have verified that they work on the older 2700/3700/2800 and 3900. But I had to put a .5sec duration for it to work correctly, otherwise I had to either tap the button twice or hold it for a little bit. If I just tapped it once, it wouldn't work.
