In continuation to my previous post, I will attempt to clarify the matter further. The content provider will make the determination as to what content will be available (if any) in the VTS (the portion of the disc which can be read by a DVD-V player). It is possible that a disc might have a MLP encoded multi-channel material in the ATS. Since a project such as this might be strongly geared towards surround playback, they could choose to include Dolby Digital in the VTS, since that would be the only way to preserve surround compatibility on a DVD-V player. If the project were stereo, then it would not make any sense to put PCM in the ATS, simply include all the content in the VTS only, as there would be no motivation to be redundant. In the end, each label will determine the type of content. We may offer a listing on our web site giving information as to the type of content available should enough people express an interest.
