Equalizing audio levels across multiple files

[Godsongz]

OK, not even close to the ideal situation here. I have a handful of .mpg video files that I need to stuff into a Powerpoint presentation. The original footage is out of my grasp, so these .mpg's are all I have to work with. The audio levels are all over the map across these files, forcing the presentor to ride the volume during the presentation, which is just clumsy.

So, is there a magic solution to this? Something I can stuff these files into and equalize the audio? Help! :)
