I have found that some channels on British Sky do show poor quality films from the USA but the DVD I was sent is good quality.
From my (32 inch LCD TV) the Black and White picture has good quality contrast and sharpness and the sound is also good. The film is continuous (without adverts) but does have a channel logo in the corner at times if I remember correctly.
I have been very pleased with it and the service
