Any particular channels you are interested in, or every channel on every satellite they have? Remember they can move channels around or transponders at will and they do move them a bit. So what you see today, may not hold tomorrow. Anyhow, the receiver will always "find them" and map then to the correct receiver channel, so I am just trying to see what the need is really.
EDIT: OK, I am too slow and that works much better. Still would like to know what the need to know the actual transmitting transponders does though.
