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...
