Got it.
V1.5 is ready.
The change to the last line is a lot less jarring, but still noticeable, because of the hiss that accompanies the LD audio.
However, being the original mix with the original sound effect, it merges better with the file as a whole.
It should be noted that the new BD from MGM doesn't have the original mono, even in lossy AC3. The reviews are yet to be out, even though the disc itself has been released a few days ago, which is not a good sign.
