MSWebDVD Object
| Microsoft DirectShow 9.0 |
MSWebDVD Object
This component is available for use in the Microsoft Windows 2000, Windows XP, and Windows Server 2003 operating systems. It may be altered or unavailable in subsequent versions.
The methods, properties, and events of the MSWebDVD object enable an application to control all aspects of DVD-Video navigation and playback, and to retrieve information from the disc. The MSWebDVD object does not perform the actual navigation work; rather, it passes the commands to the DVD Navigator filter, a Microsoft® DirectShow® component that reads DVD-Video discs.
The MSWebDVD methods and properties act on the current state of the DVD Navigator or the information on a disc, or both. To store and retrieve various types of application-specific information in the registry, such as user preferences for parental levels and default language, use the methods of the MSDVDAdm object. Use the DVDAdm property to access this object.
- Note As of DirectX 9.0b, the MSWebDVD object loads only in trusted zones. It will not load in non-trusted zones.
