We're first time, new owners of S3HD. However, the various sounds that Tivo makes when using it (especially when amplified through the home theatre speakers) drive the dogs crazy. Sometimes I remember to mute the amp first but that's not very helpful when skipping through a commercial. Is there some way to silence all of the "tivo sounds"? Secondarily, does it hurt (power consumption, heat, etc.) to leave Tivo on all the time. If you set standby, you see the record lights but can't monitor what's taping. Many thanks once again.
