I think I know the answer already, but I thought I'd ask anyway. I have a Sony STR-DE805G receiver controlled by the RM-VR1 "Egg" remote. According to [Link: remotecentral.com] most universal remotes won't work with this receiver. I have an RS 15-1994 remote and I only want to control the volume on the receiver. Any chance that I can do that with this remote? Thanks!
