I feed my Tivo box to my whole house. My main TV is connected to it through my A/V Reciever via HDMI (using DD) so I don't get the sound on that TV. I do hear it on the TV upstairs, that is connected via RCA to a Coax Modulator that then feeds my entire house.
One day I will decide to get HDMI to my upstairs HDTV (I still have an old school non-HD TV in my bedroom), but until then I laugh every time I hear the be-boops playing though my upstairs TV even though I am downstairs where it doesn't sound.
