Menus and VTS Blocks

All menus in a VTS must use the same video and audio settings, including formats, aspect
ratios, resolutions, and in the case of audio, sample size. For example, if you have some
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.
