I prefer to use live musicians and not sing to a track

You can still use the Accompaniment DVD and your performance can still be synchronized to the movie footage…just simply conduct to the Click Track while your accompanist plays live. You can subtly mix in a little of the String Section Submix (without reverb) to help supplement your sound without it feeling like you’re singing to a track. Also, consider using a supplementary keyboard to play the Simplified Strings part and/or Simplified Brass part.
