Playable on DVD-Video and DVD-Audio players

On a DVD-Video player the first menu will present you with a choice of two audio streams - two channel (UHJ encoded) PCM, which is equivalent to CD-Audio, or four channel DTS. If you have a Surround Sound playback system including a DTS decoder you should choose the DTS option. Otherwise you should choose the 2 channel version. You can switch between streams during playback using the Audio button on your remote control.

On a DVD-Audio player there are no menus - the disc behaves in a similar way to a CD. There is only one audio stream available on DVD-Audio players - 4 channel MLP. All DVD-Audio players are capable of decoding MLP. If your DVD-Audio system is configured with only two speakers you will hear a downmix derived from the four channel version, which is different from the two channel (UHJ encoded) version available as part of the DVD-Video area of the disc.

The four channels in the DTS and MLP streams have been derived from the original recording masters using specially optimised Ambisonic decoding software. The four channels are front left and right, and back left and right. The centre and LFE channels are intentionally silent. The decoding software assumes the speakers to be arranged in a square with the listener in the middle. Tests have been performed using a variety of speaker and listener positions, and this target arrangement has been chosen as a compromise that works well for a variety of speaker positions. Material decoded in this way works particularly well with the standard ITU speaker layout which may be recommended by your home theatre amplifier supplier.
