Default Wondering about audio with replaced elements

So I've noticed in some reviews on the site (eg, Terminator, Man With No Name that the reviewer mentions the mix for the film's audio has had parts of it replaced. Why do they do this? Is it in order to create a surround mix? Can't they can't just back to the original tracks and remix it using those? Is there any way of knowing whether a mix on a Blu-Ray disc uses the original elements or not, or do you just have to compare with older versions?

Psycho's 5.1 mix is another example of a soundtrack with replaced sound effects...

WrestleMania XXVII has "replaced elements," as well, and they stand out, unfortunately, as they sound different than the music and crowd reaction live.

The Good, The Bad, and The Ugly did this because the audio portion of the deleted scenes they added in were lost. So a 95-year old Eli Wallach was better than silence in those scenes.

They also added in new gunfire and explosions in TGTBATU to make the 5.1 mix.

Jaws is quite a famous one - if memory serves it won an Oscar for it's sound effects (on the orig mono track) but the 5.1 mix on the DVD used new sounds and not the ones that had won the award.

There are two ways to do a 5.1 remix from a mono soundtrack. The cheapest and laziest way is to just run the original mono mix through some electronic processing to add fake stereo dimensionality and steer some of the sound effects to different speakers. This generally sounds like crap.

The better option is to locate all of the original individual sound elements and rebuild the soundtrack into a brand new mix. When done well, the sound editors and mixers should attempt to emulate the general feeling and tone of the original mix as much as possible, but just add a little breadth to it. When done poorly, the mixers try to jazz up the soundtrack to sound more like modern movies.

In some cases, the original audio elements may no longer be available, or may have deteriorated and not be in a usable condition for a new remix, which will necessitate replacing them.

In the case of The Terminator specifically, a lot of the sound effects (especially gun shots) were replaced with new effects that sound nothing like the originals. The most famous example is the scene where the Terminator busts down the door to kill the first Sarah Connor. Originally, his gun fired with a BOOM BOOM BOOM. It was exaggerated for effect, but definitely worked for the scene.

The new version is more of a TWIP TWIP TWIP like the gun has a silencer or something (which it visibly doesn't). This creates a visual and audible disconnect whether you're familiar with the old version or not. The gun that he's holding simply should not cause that sound. They might as well have put in a phaser blast sound from Star Trek.
