Yep.  LIRC has no concept of Window focus because LIRC is often used for
things that have no windows to focus (i.e. my Internet radio script). 
Instead LIRC /always/ sends command strings as specified in the LIRC
configuration file (typically ~/.lircrc) to /all/ clients.  It is
completely up to the client to determine whether or not the action
should be performed at the time.

When MythTV starts another application, it stops listening to LIRC
commands until the other application exits.  If you start an application
on your own, Myth has no way of knowing it should ignore the LIRC commands.

Start the other application through MythTV (look at the EXECTV examples
in /usr/{,local/}share/mythtv/tvmenu.xml and note that there is an EXEC
equivalent for when you start an application that doesn't need a capture
card).

The only other option is to use LIRC modes (
http://lirc.org/html/configure.html#lircrc_format ), but this approach
requires a lot of setup (possibly with redundant configuration
information--depending on how you want your modes to work), requires
synchronizing the "current" mode for all applications (
http://lirc.org/html/lircrcd.html ), as well as UI issues (having to
devote buttons specifically to entering and exiting modes and/or having
to remember which mode you're in).  In other words, you probably don't
want to do it (I know I don't, and I actually did it once just to verify).
