I have dishnetwork, with a DVR 622... Tv1 is connected with HDMI.. Now TV2 is using a coax cable from the box to the tv. My question is.. is there a converter you can buy to hook up between the coax to the tv.. So I can get HD channels on TV2... Considering the box already has its own built in converter for TV1, since they use (coax cables) to run the receiver to the satelite... If thats the case then I would think somebody would offer a converter or have a way to make it so you can still use a external converter for TV2... So you can get 1080p.
