Ron - Thanks for the quick response. I tried the STR-GD710 method. The only input button I have is "INPUT MODE" (I also have an input selector nob). With the receiver off, I hold the "INPUT MODE" button and hit the power button. The receiver powers up, but it does not seem to change modes. Also, the RM-AAUA21 still controls the receiver and my older Sony remote will not control the receiver.
Should the receiver indicate the mode has changed to AV1?
Any more suggestions?

The instructions for the STR-DG710 should work on your
720, since the receiver is similarly set up, and the RM-AAU014
used on the 710 is very similar to the RM-AAU021 used
on the 720.
Try them and let me know if it works.
Also, the note about the RM-AAU014 not being able to change
the command mode on the remote will probably apply to
