Interesting. Problem is that if I include the "blaster" section (or, it 
seems, any part of it), irsend stops recognizing anything.

For example, if I remove the entire section for "blaster":

$ irsend LIST "" ""
irsend: Hauppauge
irsend: hauppauge_pvr
irsend: Hauppauge_350
irsend: Hauppauge_WinTV_Nexus-S
irsend: Hauppauge

If I include the blaster section in its entirety:

$ irsend LIST "" ""

If I replace the hauppauge_pvr codes with blaster codes, replacing 
"begin codes" with "begin raw_codes" and continuing until "end raw_codes":

$ irsend LIST "" ""

If I replace the hauppauge_pvr codes with blaster codes, leaving the 
"begin codes" and "end codes":

$ irsend LIST "" ""

If I download the lircd.conf from 
http://www.blushingpenguin.com/mark/lmilk/lircd.conf and try that, 

$ irsend LIST "" ""

Why should this be? How can I send a blaster code?


Kind regards,
