It's quite common is bash scripts to define a function named die:
die() {
echo "$@"
exit 1
}
If you define that at the top of your script you ceplace the above with this:
> vobcopy -m || die "vobcopy failed"
> mkisofs -dvd-video -V $TITLE -o $FILENAME $TITLE || die "mkisofs failed"
I hope you get the point...
