Non-Standard HD DVD Video Zone Files
As part of the build process, DVD Studio Pro creates two additional files in the HVDVD_TS
folder. The format process does not include these files in its final output.
• A .layout file: This file uses the disc name and a “.layout” extension. The file contains
project information used by the format process, including the marker information used
when creating dual-layer discs.
• A VOB_DATA.LAY file: This file is used for incremental builds when you choose to reuse
files in the HVDVD_TS folder left from a previous build for a new build.
Finishing a Project
Note: The .layout filename must match the disc name for an incremental build to work.

If you intend to manually copy the HVDVD_TS folder to a disc (bypassing the
DVD Studio Pro format process), you should be sure not to copy the above files to the
disc. Most DVD players ignore them if they are present in the HVDVD_TS folder on the
final disc, but some are unable to play the disc.
Additionally, if you have not saved your project before you build it, a folder is added to
the HVDVD_TS folder named Render Data. This folder contains rendered versions of any
motion menus in your project and is normally in your project’s bundle file. See
for more information on rendered menu files.
