prevent people from the popular practice of hacking the player to be able to
view all region discs. Movies, however, can still be viewed on a Multi Region
Player.
DVD-9
DVD-9 is ideally used for recording full-length movies on two layers. After playing
the first layer, users need not flip the disc to move on to the second layer.
Currently, DVD burners do not support DVD-9 discs and can only record to DVD-5
discs. You can write DVD-9 to two DVD discs for authoring, however, you will not
be able to play back the second disc since no IFO data is present on that disc. IFO
provides information on how DVD should be played back. Each IFO file contains a
"playlist" which tells the DVD player exactly what scenes to show, what subtitles to
display, and what audio track to use. In mass replication plants, two DLTs are used
to write DVD-9. This is why commercial DVD-9 titles are hard to duplicate.
• Use DVD-9 Select to allow the DLT writer to output DVD content to two DLTs if
the input disc image file is larger than 4.4GB. After the first layer is written, DLT
Writer prompts the user to replace the DLT.
• Align split point to cell boundary Select to adjust the split point to the
nearest cell boundary. For seamless playback, the split point should be set in an
ECC block boundary equal to 16 DVD blocks (a block is equal to 2048 bytes).
DLT Writer prompts the user if no suitable cell boundary can be found. Either
the original split point is kept or a newly found cell boundary will replace the old
one. The default split point value is 130310.
• Split point between layers for DVD-9 (x16 sectors) Enter a specific split
point value.
Make sure that the split point value should be ECC block aligned (1 ECC block =
16 sectors) and within legal DVD content. The size of the first layer should also
be equal to or greater than the second layer. It is also better to locate it inside a
DVD cell to guarantee seamless playback.
Output options
• Header format Select the protocol to be used to write content data to DLT.
Mastering plants popularly support DDP v2.1. But if you need to give extra
consideration to CSS and include DVD-Audio mastering capability, select CMF
(Cutting Master Format) 1.2.
• Output DDP data Select to enable DLT writer to output DDP header data to a
file. This file can be sent to DVD mastering plant for verification.
• Output control data Select to enable DLT writer to output DDP control data to
a file. Generated for the first layer, this file contains the lead-in data recorded
on the final DVD disc.
