I may have been unclear about this "replay". The brain is entirely normal and fully functioning. It's just that we "happen" to be giving it exactly the same inputs we did on an earlier run.
Are you saying that if you allow a brain to run normally then it is conscious, *except* if it happens to be given the same inputs that it had on an earlier run, then it is not conscious?
Or would you say that a brain is conscious any time it is functioning normally and processing information, even if it happens to be the case that it is repeating an earlier run? If so, you can then go and read Emlyn's and Eliezer's messages and see what you think of them.

Forget about the Turing test. That is not important here. Let's imagine that the brain is not involved with a Turing test, instead it's learning to bake a cake while telling you a funny story about when its great grandfather came home from the war. It's just an ordinary brain, having an ordinary conscious experience, like we all do all the time.
The point is not whether some external observer could determine whether the brain is conscious by giving it a Turing test. The point is whether the brain is *actually* conscious, a fact which is true or not regardless of anyone else's opinions or whether it is willing to participate in any kind of testing.
