¿aunque, podrias explicar eso de "no se atienen a ninguna norma (en cierto modo son piratas)"? me resulta interesante.

un saludo
Pues en esencia no cumplen ni las normas del cd (libro rojo o redbook) ni las del dvd (libro naranja) y son algo más gordos y pesado, por lo tanto pueden desequilibar sistemas delicados.

Copio textual de la página de Linn (hay otros)

"DualDisc format - is it a supported format for Linn disc players / audio servers?
No - DualDisc is not supported. DualDisc is a disc format with DVD content on one side and ‘CD’ on the other (see http://www.dualdisc.com for details). The DVD side comprises DVD-Video and/or DVD-Audio content. The ‘CD’ side is designed to play on CD players but is not in fact a CD as it is not compliant with the Compact Disc Digital Audio Specification (the industry 'Red Book' CD Standard). These discs are also thicker than standard CDs or DVDs.
As these discs are not compliant with current industry standard, Linn cannot guarantee that they will play on our range of disc players and audio servers. Nor can we guarantee that the thickness of DualDiscs will not cause problems for these Linn products – possibly damage to the product and/or the disc – if played. Any damage resulting from the playing of DualDiscs will not be covered by the Linn warranty, so using these discs with a Linn disc player or audio server is entirely at the user’s risk."

O sea, que como los use puedo j.der 5 años de garantía .................

Y ahora la pregunta del millon ¿para que invertar lo ya inventado?, me refiero a que metan un CD y un DVD en soporte independiente o ¿es que la discográficas se van a arruinar por comprar un CD adicional a precio de mayorista?
