Advertisements I have my Tivo HD connected to my projector via a hdmi to DVI adapter. Audio goes to my receiver via optical cable. I notice that when I switch the input on the projector from DVI to component (for the x-box or dvd player) the audio output of the tivo stops, even though I have not yet changed the input on the receiver. When I switch back to the dvi input on the projector the audio returns. This is very convenient and I like it but I'm not sure its supposed to do that. I would think the digital audio output from the tivo would continue no matter what the projector was seeing.
