I have also found the following information on wikipedia:
Oxygène: New Master Recording, also known as Oxygène New Master Recording 2007 and Oxygène (New Master Recording), is a new recording of an album by Jean Michel Jarre released in 2007, marking the 30th anniversary of the worldwide release of his album Oxygène, and is Jarre's fourteenth studio album. It is his first release on EMI Records.
The album was released in three different editions: a 5.1 Music Disc edition featuring the new digital master recording of Oxygène, a CD and 2D DVD special edition featuring Oxygène — Live in Your Living Room DVD (an exclusive private live performance of Oxygène, filmed in Lint, Belgium), and a limited edition CD + 3D DVD featuring Oxygène — Live in Your Living Room DVD in stereoscopic 3D High-Definition, which also includes two pairs of 3D glasses.
-> So it appears that there was a version with a 5.1 Music Disc ( which is equal to
a dts CD ) so it appears to be legit.
