The remote codes included in the manual don't work and I tried the on-screen method as well and no worky. "Learning" didn't work either, at least I don't think it did because I'm not totally sure I understood the manual on this method.Anyway, does anyone know if this Onkyo remote (for the TX-NR807) is capable of connecting to this HD-DVR from DirecTV, or am I wasting my time? This is driving me up the wall! Thanks to anyone in advance who helps me with this!
