Hey guys, I just wanted to see if anyone has any ideas about this. I just got the Vizio Co-star to use with my Comcast Motorola DCX3400 and no video or audio appears at all. I've tried: - Unplugging all power to DVR, Vizio Co-star, Vizio TV - Replacing HDMI cables - Changing all meu options on the DVR - Performed a factory reset on all devices - Calling Comcast Nothing works for me. Any ideas guys? Thanks!
