Comments

This function does not support command synchronization.

The title currently being played determines which subpicture streams are enabled and disabled. The title must enable a subpicture stream for it to be displayed. The programmer can retrieve the subpicture stream status by calling IltmmDVDControl::IsSubpictureStreamEnabled.

Call IltmmDVDControl::get_SubpictureOn to retrieve the current subpicture display status.

For more detailed information, refer to the Microsoft documentation for IDvdControl2::SetSubpictureState.
