I just upgraded my 625 receiver to a 722k and now I can't get the CC to work. This is a Visio LCD tv and I was using its own remote to turn on/off the CC. Some functions like volume still work with the Vizio remote but not the CC. The only other change that was made was connecting the TV to the receiver via HDMI. Is there anyway to activate Close Captioning via the DISH menu and/or remote?
