ltmmDVDControl.IsSubpictureStreamEnabled Method
Remarks
Determines if the specified subpicture stream is enabled in the current title.
The ltmmDVDControl.SubpictureStreamsAvailable Property contains the number of available subpicture streams.
The ltmmDVDControl.CurrentSubpictureStream Property contains the current subpicture stream.
The title currently being played determines which subpicture streams are enabled and disabled. While setting a disabled subpicture stream as the current subpicture stream will not return an error, the program will not display subpicture data until it plays a title that enables the stream.
