Comments

The title list can be modified at any time before writing the menu. A maximum of 36 titles can be added. Calling ILTDvdWriter::AddMenuTitle with an existing index will not make an update: it will insert a new title at the specified index and shift the list down.

Menu writing should be the last step in a DVD image authoring process. Writing the menu first will cause an error and if a new title is written after the menu has been written, then the menu will be destroyed.

Any multimedia file can be used as the menu background, including a single page image, a multipage image, or a video. All menus require a background video. To add menus to the DVD image, perform the following steps:

Add menu titles by calling the ILTDvdWriter::AddMenuTitle function.
Call the ILTDvdWriter::put_TitleMenu, passing VARIANT_TRUE to the newVal parameter.
Convert the background image for the menu. This is a standard DVD conversion graph, only the video will be used for the menu background.
Call ILTDvdWriter::put_TitleMenu, passing VARIANT_FALSE for the newVal parameter to close the "menu write" mode. This merges the menu subtitle information with the background video and modifies the DVD image.
