In the UK (and a lot of Europe) we sometimes have a narration track in addition to the regular AC3 surround track, this is audio with scene description for the blind. Of course not all programmes actually have narration tracks so often this ends up being just a stereo track, I suspect due to the common problems with dialogue getting lost in surround sound mixes this additional track is usually mixed differently with much more forward dialogue, sometimes it's useful for that on it's own.

Maybe there's a similar situation for you?
