| It would seem to me that the easiest solution to your problem would be to adjust the boundaries between the AppleScript part of your solution and the shell script part of a solution, just a little bit. You want to write the shell script so that it doesn't need to be edited, and so that all the variability is in the AppleScript.
Being slightly more concrete, I believe that you want to write your shell scripts so that everything that might need to be changed by the AppleScript is represented as a parameter rather than as a hard-coded string. Then the AppleScript needs to determine the correct value of the parameter at runtime, and pass it as an additional argument in the "do shell script" command string.
In your particular case, I believe that the result would look something like this (and I'm not being very specific, because I haven't personally worked with AppleScript bundles):
In the shell script:
function convertFile() {
/opt/darwinports/bin/ffmpeg -y -i "$3" -i "$1" \
-target pal-dvd -aspect 4:3 -acodec mp2 -ab 128a \
-vcodec mpeg2video -b 3000 -g 25 "$2"
}
convertFile "$1" "$2" "$3"
In the AppleScript:
set convert_shell to (quoted form of (POSIX path of ((path to me as text) & "contents:resources:loud_convert")))
set SilencePath to (quoted form of (POSIX path of ((path to me as text) & "contents:resources:silence.mp2")))
set thecline to (convert_shell & " " & POSIX_path & " " & ConvertedFilmsPath & " " & SilencePath)
do shell script thecline

Now this seems to be a bit of a brain teaser, but it might seem a stroll in the park to some of you... So:
I’ve got an application bundle written in AS that alllows me to convert most films into mpg2 films. I use it in drag ‘n’ drop. I call a do shell using a shell command included in the bundle, thus:
set convert_shell to (quoted form of (POSIX path of ((path to me as text) & "contents:resources:loud_convert")))
set thecline to (convert_shell & " " & POSIX_path & " " & ConvertedFilmsPath)
do shell script thecline
That’s fine when the shell (loud_convert) doesn’t need to have an extra resource. But if I want to use an extra resource such as a silent audio track (to have a muted film), the shell (mute_convert) needs to be edited. Is there a way to edit a bundle resource on the fly ? If so a working example would be much more precious than a simple “yes”... :-)
