Brian,
There is a way to accomplish a "virtual volume lock" that will ALWAYS control the RCVR volume. My RCVR is AUX2. I want to use "virtual volume lock" in the CBL/SAT, AUX1 (DVD), and VCR modes.

Here's my setup for "virtual volume lock":
CBL/SAT * P *--** 9*9*4* AUX2 VolUp * VolUp **
CBL/SAT * P *--** 9*9*4* AUX2 VolDn * VolDn **
CBL/SAT * P *--** 9*9*4* AUX2 Mute * Mute **

Repeat that sequence, replacing the "CBL/SAT" with the other divice codes that you want to use the RCVR vol/mute.
