lirc problem

[Sim1]

Lircmap.xml file in .xbmc/userdata might have changed since Frodo or remote.xml in .xbmc/userdata/keymaps (if in use).
If I remember correctly first file translates lirc events (the ones displayed by irw) from specific remote (you can have many remotes mapped in the file) into commands (or you could call them 'buttons') that the other file translates it further into xmbc actions. The second file might not be present then default is taken from system xbmc folder.
