Handbrake movie audio voices

Hi,

I encoded some movies in HB and the voices don't seem proportionate to the gunshots etc.

The gunshots are really loud and the voices are rather quite?

I used the Apple TV preset for audio - is there anything I need to change in order for the voices to be 'normal' as they would be on a dvd?

I have to turn the volume up reasonably loud to hear them, then a gunshot goes off and it's ridiculously loud haha.

Cheers for any help!
