Audio track is the great achievement of the 2005 restoration,
This review is from: The Wizard of Oz (Three-Disc Collector's Edition) (DVD)While the visual quality is superb, the great achievement of this (2005) restoration is the audio track. As the "making of the restoration" feature points out, the original music track was recorded from 4 microphones, making it possible to restore the music to a true Dolby 5.1 track. There are sound effects I had never heard before, such as the leaves being stripped from the trees during the "twister", and the bass accompaniment to the singing opens up the dynamic range of the music.
As for the visuals, we encounter that bane of digital formats--too much perfection. The opening scenes in sepia tone Kansas are so perfectly restored that small amounts of projector "flicker" from print imperfections appear in some backgrounds that were not apparent in the first dvd restoration. Make no mistake about it, though, the sharpness and accurate color are a feast for the eyes.
If you're wondering whether to go with the 2- or 3-disc version, you'll want to know that the third disc contains the 5 silent "oz" movies made before WWI. They are not necessarily fun to sit through, but instructive to see how much of the costuming concept for the main characters seems to have been inspired by that very first effort. If you're not a film student, the 2-disc set will give you all the bang for your buck.
