I have several of each of the above controls. I recently changed my DirecTV receivers’ to HD receivers from DirecTV. The new Receivers are Models H21NC-200. Can you tell me the codes for my remote controls? DirecTV told me to contact the maker of the remotes. I also have a Zenith universal remote control Model ZN501S that I need the code for, if you can help. Victor: EMAIL = jojohome@juno.com
