Oh...see my dish boxes support hdmi, component, AND coax all simultaneously......i used one configured like that for years in my house....ran the kitchen, patio, and garage tv.....all on same program obviously, but we generally only run all the tvs while entertaining and generally that involves a game, fight, or other event we are all watching anyway....
Honestly i would be surprised if your box didnt support coax and component as well...?
