robert at mythfe2 ~ $ cat /sys/class/rc/rc0/protocols
rc-5 nec [rc-6] jvc sony lirc

I take this to mean that I have all those protocols available to use, 
but only rc-6 is active - maybe this is why you are getting multiple 
events for some buttons because you look to have two selected.

That looks the same as I have:

robert at mythfe2 ~ $ ls -l /dev/lirc*
crw------- 1 root root 246, 0 Jan  7 14:48 /dev/lirc0
lrwxrwxrwx 1 root root     19 Jan  7 14:49 /dev/lircd -> /var/run/lirc/lircd

My lircd config looks like this:

robert at mythfe2 ~ $ cat /etc/conf.d/lircd
# Options to pass to the lircd process

LIRCD_OPTS="-H devinput -d 
/dev/input/by-id/usb-Formosa21_SnowflakeEmulation_C01245B8-event-if00"

and I have the lirc conf file linked to the default devinput sample 
installed with lirc:

robert at mythfe2 ~ $ ls -l /etc/lirc/lircd.conf
lrwxrwxrwx 1 root root 52 Aug  5 19:54 /etc/lirc/lircd.conf -> 
/usr/share/lirc/remotes/devinput/lircd.conf.devinput

and then I have .lircrc in /home/mythtv where I setup my key mappings:

robert at mythfe2 /home/mythtv $ cat .lircrc
# Keymapping for RC-6 remote
# RL : 2011

begin
   prog = irexec
   button = KEY_POWER
   repeat = 0
   config = /home/mythtv/bin/suspend.sh
end

begin
   prog = mythtv
   button = KEY_CHANNELUP
   config = Page Up
end

begin
   prog = mythtv
   button = KEY_CHANNELDOWN
   config = Page Down
end

.... etc.

Cheers,
Robert.
