Purchased the URC-6131 to replace my remote for my sony standalone Tivo. I may have a stupid questions so please bare with this newbie. With the sony remote, it would control the sound on the TV (Sony Wega) and the Tivo with out switching anything. With the URC 6131, i have to go from PVR to TV to adjust the volume on the tv then back to PVR. Is that the nature of this remote or am I missing something. Thanks in advance for any help...
