From your post that I originally quoted, in conjunction with the screenshotted excerpt from the FAQ you attached to it.
Short summary would be: the answer to that question makes no sense to me.
Specifically, I am trying to figure out who this "co-actor" is and what "hard work" means in relation to that person. It can hardly be the VAs - their, uhm, "lines" had already been recorded, there is no more "work" for them in regards to creating a copy of that specific product. The editor, then? Because they would be the ones putting everything together once more (excluding the male audio track this time).
