Comments

This property selects a subpicture stream. To get the count of available subpicture streams in the current title, call the IltmmDVDTitle::get_SubpictureStreamCount property.

To examine each subpicture stream use the IltmmDVDTitle::GetSubpictureStream to get each ltmmDVDSubpictureStream interface. To examine the subpicture stream information, decide which stream you want to use and then select it using the IltmmDVDSubpictureStream::put_Selected property.

It is best to include the LEAD Video Subpicture Mixer with your application if you want to convert DVDs with subpicture information. This filter is needed during conversion if the DVD decoder does not combine the subpicture information with the video. If the DVD decoder does not combine the subpicture information with the video and the LEAD Video Subpicture Mixer is not present, it will appear as if you never selected any subpicture stream during conversion. This is true especially for Vista and Windows 7.
