Common DVD content

What one finds on the DVD side of a DualDisc title will vary. Common content includes:

Audio types

The CD side of a DualDisc contained standard 16-bit LPCM audio sampled at 44.1 kHz. On the DVD side, most record companies (with the notable exception of Sony Music: see below) provided the album's music in both high-resolution, 24-bit DVD-Audio (typically at a sample rate of 96 or 192 kHz for stereo and 48 or 96 kHz for surround sound) and lower-resolution, 16-bit Dolby Digital sound (typically sampled at 48 kHz). This was done to allow consumers with DVD-Audio players access to very high-resolution stereophonic and/or surround sound versions of the album, while also providing the lower-resolution Dolby Digital stereophonic and/or surround sound which is compatible with any DVD player.

Sony

Because Sony had an existing high-resolution audio format, SACD, in the marketplace which directly competes with DVD-Audio (see next section), Sony Music, as a general rule, only provided 16-bit, 48 kHz sampled LPCM stereophonic (and sometimes Dolby Digital Surround) sound on the DVD side of their DualDiscs. The sound was compatible with any DVD player; however, it does not provide the higher fidelity and resolution of 24-bit, high sample-rate DVD-Audio.

In addition, several SonyBMG titles whose regular editions include copy protection programs (such as XCP and SunnComm) did not feature the software on the DualDisc versions.
