Handling Disc Ejections

When the user ejects a DVD from the drive, the DVD Navigator sends your application an EC_DVD_DISC_EJECTED message. The application can safely ignore this message and let the DVD Navigator manage the graph's state. An application can also handle the EC_DVD_DISC_EJECTED method to implement custom behavior when a disc is ejected. If you handle the message, you must set the DVD_ResetOnStop flag to TRUE with the SetOption method and then call IMediaControl::Stop before closing the application or playing another disc.
