--- Comment #8 from Zeb Figura z.figura12@gmail.com --- Ugh, I managed to miss one critical line in the log. It's not failing the callback because it doesn't want the VMR. It's failing apparently because it's trying to configure the VMR from within the callback and it's too much of a stub. This'll need some work.
