Cable should be connected to the tv. Then tv's second hdmi to rocketfish wii to rocketfish. That should do it. Because the cable plays through the tv. Rocketfish allows pulling the xtra into one loc so u don't have to plug and unplug. Really dvd, plug into rocketfish too. Cale in one on tv, the other connect to rocketfish. Wii and dvd connect to rocketfish ports. U will need hdmi for each and the appropiate lengths for each as well. Depends on the distances from dvd and wii to rocketfish as well tv to rocketfish. I do hope this puts it together for you. My son has cable connected in first hdmi port, second port connection tv to rocketfish. PS3 and PS4 from each out to rocketfish. Tv is source of viewing for them all. But cable need only connect to tv
