For example, for a DVD called "My Summer Vacation," you might have the titles "Water Skiing," "New Friends," and "Hiking." For each of those titles, you might have one or more different video files..
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.
