Menus and VTS Blocks
All menus in a VTS must use the same video and audio settings, including formats, aspect

menus using AIFF audio and others using AC-3, they must be placed in different VTS
blocks. DVD Studio Pro automatically places menus into VTS blocks as needed by their
Each VTS in an SD project is limited to a single file to hold the menu content, with a
maximum file size of 1 GB. If you have a lot of motion menus, you may exceed this limit
and need to split the menus between multiple VTS blocks.
Note: A single VTS in an HD project can contain up to 99 1 GB files for menus.
