I'm looking for a Volume controller for my mac mini at work. We use it as a Video player for our advertising mode, and we use VLC player because, personally, I like its playlist method better than most other solutions. Any ways the problem comes in that we have different media formats ie. vob, avi, mpg. So I'm looking for a coverage app that will dynamically read the current volume level and adjust it so that it always meets a predetermined level.

If such a program exists let me know that would be great.
Thanks
