DVD-Audio discs will play in any DVD player, but will not have the higher fidelity sound.
There is a 5.1 soundtrack on the disc that is the same quality as a DVD movie. It's compressed audio. There is also a true DVD-A track that only a DVD-A compatible player can play. This track has higer fidelity than a CD or a DVD movie.
This system is much like the current SACD/CD dual layer discs. When played in a CD player, the CD track plays. When played in an SACD player, the SACD track with higher fidelity plays.
Most audiophiles believe a normal CD has better sound than a DVD-A played through a DVD player because of the lack of compression.
