Hi Edoardo,
Does the audio works well in author?
The reason it says "Instructor" is that because if you give the sequence to some other teacher and he/she is using it with another LAMS server, it won't have your name, as that server might not have your user details. Therefore when we create a lesson based on a sequence, the user we put is "Instructor" rather than the person that authored or even started the lesson.
Forum, for example, also behaves in the same way. When you see the messages that you added in Author, when you see them in learner, you'll see that it also reads "Instructor"
Thanks,
ernie
