Henni,
I think you got me with this one. Two issues on my end. I don't have an Audya to mess with
As you mentioned, it does sound like you might be trying to do something that is a little different from what I tried. I was just poking around looking at the "RAM INS" folder but at this point can't explain how those map and how/if they could be modified in any way.
Now, I'm on a mission to better understand that section of the unit now that you pointed it out.
