I was watching Roots (episode 3) and noticed the weirdest thing. When the film opens, the music sounds as if someone turns it down. Briefly the sound effects from the horses sounds was louder than the music, followed by the music getting louder,and then soft again. Upon looking at my vhs copy, this does not occur. The Spanish track includes a narrator during this section of the film in the exact same spots that the music get soft. Could this be in error in the authoring of the 1.0 mono, or is that even possible since it is just one track? Help!
