correct me if i'm wrong, but what i'm reading from your posts is that
you purchased an IR Blaster and have that installed. your 'TV'
service has a set top box that you currently control with a dedicated
remote. you already have a wireless keyboard and mouse hooked up and
working with your MythBox.
is that correct?
if so, (and list, please correct me if i'm wrong as i don't use this
setup) you 'may' be able to use the IR receiver that your keyboard
uses to get button pushes from your remote into Myth. LIRC will then
decode them and control the various Myth functions. if you want to
change channels on your set top box you will still need the IR
Blaster, so Myth can tell your STB to change channels.
forget the IR Blaster and the on order IR receiver for the moment.
look over the wiki and in the archives for details on how to use
'irrecord' and 'irw' to create your own lircd.conf file. it's
actually very easy to do, and then you can customize it for your
remote and your preferences. try to use irw and irrecord to capture
button presses from your remote pointed at your wireless keyboards ir
receiver that you have hooked up to your MythBox. if irw is able to
receive signals then you can return the IR Receiver that you just
ordered. after you've played with and tweaked your newly created
lircd.conf file (following the instructions on the wiki) you can go
about setting up the IR Blaster to change channels on your STB from
Myth using your harmony remote.
i hope i didn't muddy the water any with my comments. i think you
just need to start at the beginning and take it one step at a time.
it sounds like you're trying to get too many different pieces to work
hope that helps

Honestly, I didn't even think that the IR receiver for my wireless keyboard
would be able to accept those remote commands. If it can, that would be
great, since all I really want is mainly to hit the down arrow on the remote
and have the menu item go down by one. Maybe be able to control xine or
mplayer if I'm watching videos (pause, FF, etc.) as well. I will look into
the wiki and see if I can figure out something. I'm not computer illiterate
by any means, but some of these concepts in Myth are very new to me (lirc,
TV capture cards, etc.), so I'm still learning as I go, which can only be a
positive in the long run.
Thanks, and I'll keep you posted.
