The file $HOME/.lircrc is where you put lirc config for programs like
mythtv.  The default .lircrc file contains "include" lines for other
files put in $HOME/.lirc which is where you put your actual lirc
config for each program:

include ~/.lirc/mythtv
include ~/.lirc/mplayer

So for MythTV, you put the lirc config in $HOME/.lirc/mythtv, which
should already have the default config.

But, the file name does not actually have any meaning.  You can have
lirc config for any program in any of the included files, or directly
in $HOME/.lircrc.  What tells lirc which program the config applies to
is the "prog =" line in each rule in the config.  Here is an example
from my $HOME/.lirc/mythtv file:

begin
    remote = devinput
    prog = mythtv
    button = KEY_EXIT
    config = Escape
    repeat = 0
    delay = 0
end

So, the "remote = devinput" line must match the remote configured in
/etc/lirc/lirc.conf.d/devinput.lircd.conf, and the "prog = mythtv"
must match the lirc name used by the program.  All MythTV programs
(mythfrontend, mythtv-setup.real, mythavtest) use the lirc name
"mythtv".  If the remote and prog lines match, then the "button ="
line can be matched against an incoming keystroke, so if KEY_EXIT
arrives, it will match this rule and then the "config = Escape" line
will be used to tell lirc to pass on the string "Escape" instead of
KEY_EXIT.

In your case, as with me, irw is showing that your remote is matching
the "devinput-32" config in /etc/lirc/lirc.conf.d/devinput.lircd.conf.
Since your $HOME/.lirc/mythtv file will almost certainly be using
"remote = devinput" instead of "remote = devinput-32", there will not
be a match and lirc will not send mythfrontend any keystrokes.  As I
explained in my other post, you need to edit
/etc/lirc/lirc.conf.d/devinput.lircd.conf and change the "name
devinput-32" line to "name devinput" and restart lircd:

sudo systemctl restart lircd

Then restart mythfrontend.  Or you can also test using an "ircat
mythtv" command (while mythfrontend is not running).
