I know this thread is a year-and-a-half old but I want to say a big Thank You to fishin'.
For
three years I've been constantly pressing the AUX and SAT buttons to alternate between controlling the volume of my Sony STR-DE945 and the rest of the controls on my satellite receiver. In the PDF you mentioned for this remote (which I have) it gives a button sequence to control the AUX volume from any mode, including SAT.
fishin'- you're a life saver, I would sacrifice a small cow- if I had one- in your honour.
Thanks a lot.
