I am researching the same issue as I am trying to connect 2 TV's to my Roamio Plus. One via HDMI and one via Component. The HDMI output works fine but I don't get any signal on the Component side. I found this seemingly official response from a Tivo support person: "because the TiVo Requires an HDMI handshake from the TV trying to send recieve the TiVo through a third party device would not allow the TiVo the ability to display picture." http://forums.tivo.com/pe/action/forums/displaythread?rootPostID=11156626&nextElementId=11146222 That seems to imply this won't work or am I missing something?
