Low dialog on Blu-Rays

[MagicSeaMonkey]

I have a Mitsubishi LT-52149. It has one of those sound bars on it, and usually it's awesome, but there are some movies where the dialog is just drowned out by all the other sounds in the movie.

I tried to Google this problem, and several results pointed to the fact that audio comes out of a "center speaker" or something and that it might fix the quiet dialog problem if I were to raise the volume of this. Unfortunately, I can't figure out how to do that, or even if it's possible. Being a sound bar, I'm not sure. The instruction book that came with the TV doesn't say you can do it.

There is also no option on the Blu-ray movie itself to amplify the dialog. My Blu-ray player is a Sony BDP-S350 and there doesn't seem to be any options on it that help it out either.

One thing that kind of works is to set the "Level Sound" option on the TV to "On" so that it levels out all the different kinds of sound. It's an okay alternative, but it's really not that great. At least you can usually understand the dialog if it's used.

Anybody have any suggestions? Thank you.
