I just bought a Sony GX 355 dvd recorder to record shows off of my 10-250. I have it hooked up with HDMI out of the TIVO to my television and component out into the dvd recorder. I can only get audio to record. Do I have to disconnect the HDMI from the TIVO while trying to record or can the 10-250 run at the same time component out- HDMI out ??
