I see on the TiVo screen an option that says: Part 2: A/V volume and mute I've gotten the remote to change the volume and mute, but how do I get it to turn it off? Does the remote control indeed do that? The TiVo site says it does... but I'm not sure how to do it? From TiVo: Control power, input, volume and mute of your TV and/or audio receiver. I don't see where it actually powers the sound system on and off though.
