Because MVS's audio isn't actually stereo, it's just mono audio with each channel being the inverse of the other. Just like when you add an inverted image to the original image, adding the inverted audio channel (say, the left) to the original audio channel (say, the right) will cancel each one out. I'm assuming you're playing this back on a TV with a single output, or at least a setup with a center channel speaker that is suspiciously quiet when watching the movie. That is why.
There's usually a minor difference between the left and right due to mp3 compression, and sometimes an additional delay, which makes each channel not cancel out completely. In this case you'll hear a little bit of noise but not much else.
In short, this is another big problem I have with MVS as a group. They release this "fake stereo" audio in a lot of their releases, and though it sort of sounds like stereo audio (because your left and right ears hear slightly different things) it isn't actually stereo audio. Instead we wind up with playback issues on non-stereo TVs and decent home theater systems, in addition to the wasted bandwidth that could have been saved by encoding the audio as a mono (or at least joint stereo) mp3.
