Hey friends I am a comcast customer and well just recently, some of the channels like TNT, The Weather Channel, Cartoon Network, etc. are not working. The channels have this message “We’re enhancing our network. Order digital equipment for all your TVs to continue receiving all your channels” but I dont want to order a comcast box. My plan was to get a QAM Tuner box, but I dont know if that is good. If it is, where do I buy this tuner box please suggest?
