Instructions on IR database?

Are there any detailed instructions on the Generic IR database and how to get that set up? What I read was vague and not much help. I'm trying to get our Dish Hopper 3 integrated. I also have a NAD M33 that's not on the list, but figured I'd test some of the other NAD processors and see if any of those work, or if the SmartRemote can learn IR, instructions for this would also be helpful.

Did you look at this documentation? Not sure if it's as detailed as you want but might help.
