Driver correctly handles media types, time discontinuity, and decode-rate adjustment. [VID-0218]
All DVD video decoders must support Line21 closed-caption data. [VID-0223; see FAQ B22.214.171.124]
All MPEG-2 decoders can accept an MPEG-2 elementary Stream. [VID-0216]

Windows XP: DVD decoders must use the operating system’s native file system support to read DVD drives; alternatively, for SCSI devices, requests can be passed using IOCTL_SCSI_PASS_THROUGH. The decoder must not use non-Microsoft drivers to read the content of DVD drives.
B126.96.36.199 DVD-Video navigation requirement [Logo Program Clarification]
The motivation for the requirement is that software vendors need a standard interface to DVD-style MPEG playback. This is necessary for such applications as games that include MPEG video, Microsoft PowerPoint® presentations with video, WebDVD applications, and encyclopedias such as Microsoft Encarta® or Compton, and to allow users to exchange MPEG files for display on different PCs.
Windows 98/Me: Windows Logo testing requirements:
WHQL testing will ensure that software decoders work with the Microsoft Navigator and the Microsoft DVD Player application runs on OEM systems that support DVD playback.
WHQL will not test OEM systems to determine whether a software DVD player is talking with the software decoder by way of the Microsoft Navigator. Any third-party navigator must use DirectShow and support the same interfaces as the Microsoft Navigator.
A DVD player application can talk privately with a software decoder, provided that the decoder also works with the Microsoft Navigator.
Microsoft encourages implementers to provide Microsoft with details about additional required navigator features, so that those features can be added to the future API.

B11.2.R DVD Playback - Future Requirements
Announcement of additional future requirements will be published at http://www.microsoft.com/winlogo/hardware/video/.
B11.3 TV Tuner
All general requirements in B1.0 are included by reference.
All bus-specific requirements in B2.0 are included by reference.
All general requirements in B11.1 are included by reference.
All TV receiver modules for use with Windows XP must conform to the BDA architecture, as defined in the DirectX 8 DDK and in “Broadcast Driver Architecture Drivers” in the Windows DDK. Data streams along with video and audio streams are required to be passed into the Microsoft DirectShow environment. The IP Sink filter provided within the BDA architecture is the mechanism for getting the data to the IP software rather than using an NDIS driver for the TV tuner module.
WebTV for Windows and related DLLs are not part of the Windows XP product. All analog and digital video capture solutions must be based on published DirectShow interfaces, WDM Video Capture and Broadcast Driver Architectures.
