From the developer:
A52Codec is a CoreAudio component that can decode stereo and 5.1 surround sound from A52 and AC-3 audio. This type of audio is often found in DVD movies.
From the Developer:" I'm no longer maintaining this app as a separate download; Instead you need to download Perian to get the latest version."
