I just got the blu-ray of The Day The Earth Stood Still from 1951. One of the extras is Interactive Theremin. You're supposed to be able to put down some notes and then play it over a scene from the movie. It starts and I can put down notes. But when I click the preview button, there is no sound. Just the background sound that plays while you put the notes down. And when you click the Play button, there is still no sound. It just shows the scene from the movie. I tried the movie on my computer, but it won't load, so I don't know what the extra feature is like. Has anyone here had this problem ?
