So, I've been fighting to get the codes for my surround sound system for the past week. I have a Sony STR-750P and have had no luck either finding or learning the codes for it. Today I finally got fed up and moved my USBUIRT to a windows machine, downloaded John Rhees' Lrnhelper.exe program and went to town. It turns out the remote for my receiver sends single code bursts, non repeated. Lrnhelper has a button that lets you accept the burst. I went through and was able to successfully record and transmit codes for all the functions I want to use!! Yay!!
Then I went back and plugged the USBUIRT into my MD, booted it up and went to start adding the codes I had recorded in windows into the A/V Properties for my receiver. However, when I copy and paste the exact codes that worked under windows into the A/V properties page and try to test them, none of the work!!!!
