Thanks, it did work when receiver was change to AV2 with 4001 code. I can turn receiver on & off, volume control and that is it. How do I get remote to change video to DVD, CD, turner & etc. There are many functions on remote that do not work. Do I have to learn each function to the Sony remote (example, to change audio from 2ch to movie, to music and etc. Also to change surround sound levels, test tone & etc. How do I make these functions work. Thanks a million.
