I suppose that your remote is the one from OPPO DV-980H. Does LIRC includes a config for that remote ? If not, how did you create your /etc/lirc/lircd.conf ? This file needs to be properly configured, the key codes must match with the description otherwise things won't work as it should. Here is an example:
http://lirc.sourceforge.net/remotes/onkyo/RC-104C
The lircmap.xml is only to atribute a specific key from the lirc.conf to a Kodi action.
