Hi, I'm new to this forum and really need your help. I have a Harmon Kardon AVR 340 and I can't seem to program the DirecTV R15 Satellite reciever. I have tried the codes listed for SAT in the HK manual: Hughes - 437 , 489. Philips - 375. No Joy. I have tried to program using instructions for the Auto Search Method and also no luck. I'm not sure exactly who manufactures the SAT all I know is that it has R15 on the back and info on the web points towards either Hughes or Philips..... please help. Thanks
