Query: Rubbish. Load of Junk!

This DVD never worked. The supplier is selling bogus products. "This DVD could not be properly authenticated for playback." It is not a genuine product. The Billy Elliot synopsis worked but was just a copy of text from Wekipedia. Nothing else worked. Give your money to charity rather than but this bogus product.
