Missing key in LIRC file

[Luca C. <cas...@li...>]

Hi guys,
I found the right code for my LG DVD Recorder RH 255: 6711R1P070B
But I have a big problem: this remote is for PLAYERS, but I have a
RECORDER, and the file lacks the REC button!

Can I figure out the code for REC key starting from the attached samples of
PLAY, STOP and REC buttons? I made them using a standard IR LED and the
audio card , as I do not have a TSOP to build the proper hardware.
