I installed this for the first time today, and after hitting my head against the wall for 2 hours to get it working, I finally figured it out:
The file in MyDocs/qtirreco/Devices needs to have the same name as the name line inside it. My file was named RM-ED011 and the remote config had the name Sony_RM-ED011, as soon as I changed the file name to Sony_RM-ED011 everything worked (nearly) perfectly.

That particular remote, Sony's RM-ED011, also wasn't in the listing of all Sony remotes although it is at http://lirc.sourceforge.net/remotes/sony/ , any idea why?
