Well, If you got an MX-500 with
IRClone-MX, I could e-mail you my config file ;O) That's not a cheap option though.
If it helps, I know that SA used the same code set as the Explorer 3100 Digital box with the additional PVR keys. The explorer 3100 used an OFA (E1) remote and so their codeset will be in most (all?) OFA remotes.
Robman is the guy to help you find out if OFA has the newer codes available.
