How do I start Freevo using a button on the remote?

Question

Hi!
I've set up freevo on my computer and now I'd like to be able to launch freevo using my remote (I don't like to move out of my couch ).
I've google'd and wiki'd a lot, but I'm having trouble doing this. I came over this entry in the OS dir mail archive:

Yes!
and if how ??
Well, I am not sure if you can bind a Freevo event to shutdown but the way I do it is with irexec. Irexec is a command that comes with lirc that you can
have it run a command per button press based on configuration. In my /etc/init.d/freevo system start/stop script I have:
case "$1" in
start)
if [ "`ps -ef | grep irexec | grep -v grep`" = '' ]
then
/usr/local/bin/irexec -d /etc/freevo/irexec.conf
fi
Ok, so that't not the cleanest but upon startup it looks for a running irexec process and runs it if none is found. In /etc/freevo/irexec.conf I have:
begin
remote = hauppauge_pvr
button = Power
prog = irexec
repeat = 0
config = /etc/freevo/onoff_switch
end
So, every time that I press the power button the onoff_switch gets executed. That is a very messy shell script that decides if Freevo is running or not then starts or stops it.
The contents of that file are:
#!/bin/bash
TEST=`ps -ef | grep freevo | grep -v grep | grep -v irexec | grep -v onoff | grep -v "less " | grep -v "vi " | grep -v "cron" | grep -v "tail " | grep -v recordserver
| grep -v bitch | grep -v webserver | grep -v tv_grab`
if [ "$TEST" = "" ]
then
echo Freevo is off, starting.
/etc/init.d/freevo start
else
echo Freevo is on, stopping.
/opt/freevo/freevo stop
fi
Ok, the TEST line is horrible I know. I made that before adding pid file support to Freevo and need to fix it. Actually, perhaps I will add a 'switch' option to
my /etc/init.d/freevo and commit it to CVS.
Would others find this useful? I can use the power button on my remote to startup and shutdown Freevo with no issues.

Since I'm noobish still I really don't know what to do with this script. Am I supposed to make a sh-file with the first part of the code and then autostart the file on startup?

Put a single frame sequence structure around your stop button and then wire from the error cluster going into the error handler to the edge of the sequence structure. Now your code will stop at the end of the current iteration. To see why this works, watch you code execute with execution highlighting turned on and review the section of the manual talking about "Dataflow".
