Create a new sequence with the proper 5.1 Master audio track, and then copy/paste everything into it.
That worked perfectly. Thank you. Also, one more question. I know in stereo mode I can change the balance with the audio effect balance. Is there an effect that will move the sound from one speaker to a different speaker using keyframes?
You can place the sound with the little black puck, but at this time it's not keyframeable. You might be able to achieve that using Audition.
