I had to replace my Hughes HDVR2 (SD Tivo) so went with HD HR24-100. Previously, I connected a coax to the BR TV (old SD with only a coax input)to the coax out jack of the tivo, but the new HR doesn't have an out coax. I am wondering if I could use one of those RF modulators. I have been searching the posts and think I have the answer but I don't know if the HR24-100 sends out A/V signals on the composite jacks, S video, and component jacks at the same time, and if I can use them at the same time. The HDTV is an old Mitsubishi and it doesn't have HDMI input so I am using component video out for that TV. That still leaves the S video and A/V jacks free. I know I will have to watch the same channel on 2nd TV as the one hooked to HR. Thanks John M.
