My mom is undergoing Chemotherapy, and its really causing her hearing to deteriorate to the point she cannot understand anything on TV. Her HR20 and HR21 (Kitchen and LR) both have closed captioning, but she asked me to turn it on for her in her bedroom (D11 I think, maybe D12?) SD receiver and 19" TV, and I could find no way to turn it on. Is there no closed captioning on the SD receivers? If not, would DirecTv upgrade them to one that has CC, without a new contract?
