…yes, I understand that. The problem is that my surround mix is already mixed. I don’t want premier to muck with it, I just want premier to give me a “pass-through” to the ac-3 encoder. It doesn’t seem to have the ability for me to send my center channel audio ONLY to the center speaker and my LFE ONLY to the LFE channel. Try opening the surround mixer window and drop one of your mono tracks into the center indent on the panner. Even if you turn up the “send to center” knob only on that track, you still get audio from that track in the front left and front right channels, in addition to the center. I don’t want this to happen, since any center channel information that I wanted to be mixed into the left and right, is already mixed into the left and right before premier came into the picture.
