Hi

The box is using XMP. I found some help from "The Robman" on the forum
http://www.hifi-remote.com/forums/. As he was having a working file for the
box, he was able to give the corresponding pre_data.
The lircd.conf is now working well.

Jarod as you're now in charge of lirc, could you please tell me how to
update the lirc database, so that someone else benefit from the file (even
though) I've not recorded all keys. Should I send it to <lirc at bartelmus.de>
