I have a HVR-1950 which looks exactly like the HVR-1900. (Stupified, I can't 
see a difference!)  Using Gentoo:

$ uname -a

Linux localhost2.local 3.1.10-gentoo-r1 #3 SMP PREEMPT Mon Apr 23 08:49:39 AKDT 
2012 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux


$ eix -s lirc

app-misc/inputlircd-0.0.1_pre11
app-misc/lirc-0.9.0  "X kernel_linux lirc_devices_devinput"

(I think inputlircd, which is used for the /dev/input/event* interface, is 
pulled in by lirc -- but am not sure.)


$ cat /etc/make.conf |grep LIRC

LIRC_DEVICES="devinput"


File: /etc/conf.d/lircd
LIRCD_OPTS="-H devinput -d name=*HVR-1950*"


And, last but not least, /etc/lirc/lircd.conf contains three(?) (hauppauge?) 
remote control button configuration layouts.  I delete the two which aren't 
used here possibly saving some system resources when the file is read into 
memory.  (You need to use /usr/bin/irw to figure-out which remote button layout 
is used by distinguishing the button labels printed to stdout compared to those 
listed within the /etc/lirc/lircd.conf.)


For configuring the IR remote control to work with specif applications (linking 
remote control buttons to application specific actions such as MPlayer, Xine, 
...), create use the lircrc file (/etc/lirc/lircrc or I use $HOME/.lircrc so it 
can be configured as user instead of logging in as root).  If I'm not mistaken, 
the changes to lircrc are now real time and do not require lirc service to be 
restarted!

Also, only the lircd service needs to be started and you can omit starting the 
lircmd service.

Grep the mailing list here as I think I posted how I initially setup my lirce 
w/ HVR-1950 here.  I'm not sure how I figured-out my stuff, but did do some 
minimal tinkering and playing with command line tools to get things working.  
Lirc, including Windows IR, is a pain, but once I got it working a year ago, 
it's yet to fail.  Not like my old 29032 pvrusb2 remote which plagued me with 
IR problems.  Also, the pvrusb and lirc driver seem to be loading and unloading 
just fine on plug/unplug -- again, unlike my old 29032 pvrusb2 device.

If you want my lircd.conf and lircrc, just send me a direct email request if 
you can.  They're short, but I don't know if Mike would care for the additional 
text here.
