Comments

This property sets the subpicture stream state whether it is selected or not. Selecting a stream automatically unselects the other subpicture streams within that same title .

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 especially true for Vista and Windows 7.
