Guys, I have an old analog TV with coax connector only. I'm looking for a converter to connect FTA, DVD, and a OTA digital converter box to. Is there such a thing? Right now, I have to disconnect and reconnect when I switch from DVD to FTA, or FTA to OTA. I'd like to find some type of converter where I can connect all 3 to my TV, and just flip a switch one I'm changing from one source to the other. Thanks for your help!
