I'm running ATV OS 3.0.1 and use Sapphire for video playback. I don't have AC3/DTS speakers/system, so I assume when I'm playing videos with AC3 encoded audio there's some sort of downconverting going on (sorry, I'm not a big audiophile).

The problem I'm having is that the voices when people speak in the audio are usually really hard to hear, while the rest of the sound (music, FX, etc.) is way loud. So, we end up cranking the volume when we can't hear people talking, then the next scene is some action scene and the volume is crazy loud.

Does anyone know what might be wrong/a possible solution?

Prior to using an Apple TV I used a Powerbook with VLC and I solved this by double-processing the audio through the EQ, but there's no option for this on the ATV and I'm wondering if anyone else has dealt with this issue?

Any help would be appreciated!
