IDvdInfo Interface
- Note This interface has been deprecated. It will continue to be supported for backward compatibility with existing applications, but new applications should use IDvdInfo2.
The IDvdInfo interface enables an application to query for attributes of available DVD titles and the DVD player status. It also allows for control of a DVD player beyond Annex J in the DVD specification. Use this interface to retrieve details about a DVD-Video or about the current state of the DVD player filter graph.
