According to Dieter Dierks, CEO and founder of Germany-based DVD Plus International, the DVD Plus format, which is based on the same DVD on one side and CD on the other patent, is more compatible than DualDisc. The DualDisks currently available on the market are out of spec and therefore do not play in all players.
Dierks assumes that DVD Plus discs architecture do not exceed the 1.48 mm and can play in every player. Ordinary CDs and DVDs are 1.2mm thick and, according to specs for both media, can't exceed 1.5mm in thickness. While DualDisc makers claim their discs are in spec, industry sources have indicated that there is a problem with balance because the two layers are not equal in thickness.
Only time will tell wich format will be more compatible with DVD players.
Till now Warner Music Group has released DualDisc albums by R.E.M., P.O.D., Barenaked Ladies, Donald Fagen, and Linkin Park. The CD side of the disc contains standard two-channel, 16-bit/44.1kHz audio, while the DVD side features a high-resolution, 5.1-channel mix of the album.
BMG, on the other hand, has music videos on the DVD side of its Usher release. Sony has released DualDiscs by AC/DC, Audioslave, David Bowie, and Good Charlotte.
RCA has issued an EP-length DualDisc by the Calling. In addition to the Kathleen Edwards disc, Rounder Records is reportedly planning more DVD Plus releases this year that will have a film on one side and audio on the other. |
