The DVD version is a disappointment indeed. The picture quality is very poor, the sound quality likewise so; approximately 58 minutes into the film the sound drops out completely, leaving about a 4 second gap in the dialogue. What reliable company could have offered this product for sale to the public, knowing that these flaws were obvious? Do not buy the DVD version at any price.
