I'm glad to hear that the macro buttons have gotten you squared away.

There is a bit of a trick to teaching an audio device code to a button other than the AUD button (and as you already clearly recognize, teaching it to the AUD button would be a very bad thing as long as you want to control the 950 from the remote). The instructions for doing this are under "D:" of "Advanced Features" in the SL-9000 manual (page 33, or page 34 in the PDF file). I outlined the process in my first post of this thread, but the manual offers greater detail. The goal is to tell the remote that you are using the audio device code library to program the AUX button.

I know I've mentioned it earlier in the thread, but I have found that with most universal remotes it ends up being easier in the long run to learn commands directly from the device remote to the universal remote (assuming the device's remote is still available). If you've messed with this in the past and found it not to your liking, obviously this advice is of no use to you, but if you haven't tried this yet I'd recommend giving it a try once just to see what's involved - you may find that it is a pretty handy way to customize the 950's remote to your needs.
