Hi, I'm struggling with, what must be a simple configuration problem 
with lirc. I'm sure I must have have misssed something obvious...

I'd like to get lirc to work on a x64 Centos 5.6 based MythTV 0.24 
system. It has a PVR-350, two Nova T DVB and a DVB-S2 card.

lirc is from the atrpm's repository.

I think I might not have the right driver loaded or configured 
correctly. I have manually loaded lirc_dev but despite much googling I'm 
not at all clear what options modprobe.conf might need. Guessing, I have put

alias char-major-61  lirc_dev

into /etc/modprobe.conf

I have an IR receiver plugged into the DVB-S2 and according to 
/proc/bus/input/devices the device is /dev/input/event3

Running lircd manually and running irw in another session, I get:-

# lircd -H devinput -d /dev/input/event3 -n
lircd-0.8.7[24607]: lircd(devinput) ready, using /var/run/lirc/lircd
lircd-0.8.7[24607]: accepted new client on /var/run/lirc/lircd
lircd-0.8.7[24607]: initializing '/dev/input/event3'

But nothing appears in the session running irw.

Using irrecord I get

   irrecord -H devinput -d /dev/input/event3 irtest.txt

{snip explanatory text}

Press RETURN to continue.

Hold down an arbitrary button.
irrecord: gap not found, can't continue
irrecord: closing '/dev/input/event3'

I notice that when all irc related code is stopped I see messages like...

cx88 IR (Hauppauge WinTV-HVR400: unknown key: key=0x17 down=0
cx88 IR (Hauppauge WinTV-HVR400: unknown key: key=0x3d down=1
cx88 IR (Hauppauge WinTV-HVR400: unknown key: key=0x3d down=0
cx88 IR (Hauppauge WinTV-HVR400: unknown key: key=0x3b down=1
cx88 IR (Hauppauge WinTV-HVR400: unknown key: key=0x3b down=0

in /var/log/messages when I press buttons on the remote.

Is something else stealing the data from lirc?

cat /dev/input/event3 gives no output. But the above suggests that the 
hardware is working to some extent.

I'm a bit stumped. Any suggestions....
