Can you give me some examples of how you address the player description and "how-to's" of using different sections of the player. This would be one of those "before we begin-lets review the player functions" slides at the beginning.
I have done a grab of the player, but it looks silly having it in a graphic inside the actual course. the other thing I am doing is adding call outs placed on edge of frame that point to the specific sections. I just need a bit of inspiration to see what you all have been doing...
