Just got the Dish 522 installed, so far very happy with it. Yes there are limitations with the 1st receiver being able to "control" the 2nd receiver but as far as my needs, it is perfect. One big complaint I have is with the User guide and the remote control codes it provided. I have a Sony Receiver str-k502 and the code is not listed. I tried to follow their procedure for scanning for the code but after 30 minutes, my thumbs were ready to fall off. I have my old 301 remote and if I can figure out a way to pull off the code from that, will this work? I called Dish and they said, good luck scanning.... Can anyone point me to the location where I might be able to get the code to program in my receiver? I need to do this to control the volume of the sound, as all audio is routed through the receiver. Appreciate any assistance very much. Thanks!
