Anyone knows what these messages mean ???

Question

when i do a build-format in DVDSP i get these messages in the log :
Warning: The file ‘VIDEOGRAPHE_2006.layout’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
Warning: The file ‘VOB_DATA.LAY’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
Any idea what it means and how important they are ??? Thanks

Answer 1

As above; but it would be more helpful if the message said "FOR INFO: The file..."
from DVDSP User Manual:
As part of the build process, DVD Studio Pro creates two additional files in the VIDEO_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 VIDEO_TS folder left from a previous build for a new build.
Note: The .layout filename must match the disc name for an incremental build to work. See “Incremental Builds” on page 563 for more information.
If you intend to manually copy the VIDEO_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 VIDEO_TS folder on the final disc, but some are unable to play the disc.
