106 ULEAD DVD WORKSHOP USER GUIDE
DDPID information
The disc image on your DLT includes Disc Description Protocol ( DDP ) files. DDP
specifications describe the data to be mastered onto your optical disc including the
order in which files are to be recorded. The first file is always the DDPID which
contains records that identify additional files that make up the image such as
CONTROL.DAT and IMAGE.DAT/MAIN.DAT. DDPID information allows you to select
DDPID options for consistent output of tape images.
• DVD part version Select the DVD specification to use for the DVD content. The
default value is 1.0 for the current DVD specification. Select 0.9 for testing
purposes.
• DVD book version Select the type of media to use for DVD mastering. Read-
only disc or DVD-ROM is the default setting. Select Rewritable disc to record on
DVD-RW, DVD+RW, and DVD-RAM. Select Recordable disc to record on DVD-R
and DVD+R.
• Track path Select the structure for your dual-layered disc. In Parallel track
path discs, the first layer is read from the inside of the disc to the outside, then
the second layer is read in the same direction as the first. Opposite track path
discs have a middle area which bridges the point where the first layer ends and
the second layer starts. The second layer is read from the outside of the disc to
the inside.
If you are using a single layer disc, DVD specification still allows you to select a
track path but the DVD mastering plant will ignore it.
If you are creating two different versions of a movie such as a widescreen and a
pan & scan version on the same disc side, it is ideal to select Parallel. This is
used for projects with a variation on the second layer. The
Parallel Track Path
format is also often used in computer applications (DVD-ROM) where random
access time is more important.
• Minimum readout rate Select the required minimum readout rate of the final
disc in mbps.
CSS options and region code
• Apply CSS Select to enable the CSS mechanism. Content-Scrambling
System ( CSS ) is an encryption and authentication method used to prevent
DVDs from being copied illegally. Ulead DLT Writer supports the CSS copy-
protection method. To view the video files on the DVD, the user must use a
hardware device that is CSS-licensed to decode the data in the video file.
• Region code Displays the codes of the regions where the DVD is playable. (see
“Appendix A: DVD Region Codes” on page 111)
Big studios have also developed the Region Code Enhancement ( RCE ) to
prevent viewing a Region One disc on a Region Free DVD player. This is to
