A Media Player that increases the sound volume?

I have some movies that they have low sound volume , thus I'm looking for a Media Player that increase the sound volume by itself.
Would be OK if you introduced me the Media Player that could do it? ;)

BTW : I have win 7 x64


VLC increases the sound of the video up to 200%


I've found a Plugin for Windows Media Player for increasing sound volume.
DFX Audio Enhancement
It sounds better than VLC ;)
