On my Motorola cable box (Time Warner Cable), I use HDMI into a receiver, then into my TV for watching live TV. Does using the HDMI port make it so I cannot use the RF (Coax) Out or Component Out to my ReplayTV box (like a Tivo)? I tried the RF (Coax), but the ReplayTV isn't getting a signal from the Motorola Cable Box. Thanks for any info.
