WinLIRC works but not LIRC

[Kevin A. <ke...@al...>]

When I started building my IR Blaster, I decided to use my laptop and
WinLIRC since it was more portable. I finally got IR Blaster working and
found a remote that controls my cable box. So everything works flawless
under windows.

I found this blog posting

and I'm pretty sure LIRC is setup correctly (with my PVR-150). When I
issue a irsend commands, I see the IR LED light up (via my night vision
camcorder) but it does not control my cable box. I'm using the exact same
remote file that I used in WinLIRC.

Any ideas?
