Why do the "requirements" state that you have to have a cable or satellite box with HDMI out? What if you don't have cable or satellite and just want to do pure IPTV ? This doesn't make any sense? are they just stating this to clarify that if you did have cable or satellite that the box would have to have "HDMI" out? If that is the case they are only confusing people. YOU Can do just IPTV with this correct?
