A new multi-format audio disc that would work on any CD, DVD, or DVD-Audio player is turning out to be a huge failure:
The problem is that existing DVD players, which are designed to play both DVDs and CDs, get confused when faced with the hybrid disc. Half the DVD-Audio players used in the tests incorrectly played the Multi Format discs as simple CDs, and a quarter of them either refused to play at all or gave random results. And nearly two-thirds of the DVD-Video players incorrectly played the hybrids as CDs; and a fifth of the players refused or worked randomly.
