Ok - got it (in case anyone actually is curious someday). I've added the picture, but the key was (and I'm not sure why, yet) half (50%) glass, full (100%) movie in the mixer. And, you have to use a reference shader in order to take advantage of the animating the movie, otherwise it is all just one frame. Anyway, pictures say a few hundred words in this case, so...
