I too was led to believe this DVD would be more race oriented, rather it was how a car is built and tested, and the end result.
It was definately a great work of art, the sound of a speeding car ploughing through your living space put you in pit row...epic. The Andretti's are class, there was no ego involved with the making and any narration, Newman gave you a feeling of "Stand by Me" with his well mannered and molded voice.
Im really concerned with the way sound is reproduced with all of the latest movies, this is the only disc of the 30 I own (not very many) that with the volume a 1/4 turned up, which is usually just right with a movie, was very loud with Speedway. It wasn't distorted, the high's and low's gave me the presence I wanted when I purchased my system. Nak AV8, Pioneer 525, B&W 302's, Mirage sub...fine for basics, movies do not display the power that this disc has.
I was excited before and after I bought it, I definately want to show this disc off as a demo disc...go buy it, you won't be disappointed.
