Thanks for the replies,
I know you can download from any of the satellite slots, but that wasn't my question. I'm wondering about the download process. i.e. do the majority of you install a receiver in a complete setup with Twin/Quad/Switches, check switch, then download, or any of the other ways previously mentioned.
I find it bizarre all the ways mentioned come from the same source. Echostar Technologies Corp.'s name is on all documentation about downloading receivers, and the process is different from each one completely contradicting themselves.
I wonder if this happens within Microsoft?

just a thought.
