DLT Drives Now Work Correctly on Intel-Based Macintosh Computers
You can now format your SD projects to DLT drives connected to Intel-based
Macintosh computers.
Note: DLT is no longer an option when formatting HD projects. See “HD DVD Projects
for Replication Now Use DDP 3.0 or CMF 2.0” on page 5 for more information.
HD Project Issues
The following issues apply only to HD projects.
About Converting Your SD Projects to HD Projects
If you are converting an SD project into an HD project and intend to format it for
replication, be sure to deselect the Format for CSS checkbox in the Disc Inspector’s
Region/Copyright tab before converting the project. Since the Content Scrambling
System (CSS) is not supported by HD projects, the Format for CSS checkbox is not
available in HD projects and cannot be deselected if it was selected in the SD project.
If you have already converted an SD project that had Format for CSS selected to an HD
project, you can still format the HD project for replication if you deselect the Copyright
Management checkbox, also in the Disc Inspector’s Region/Copyright tab.
Making Your Previous HD Projects Play Reliably
The build and format functions in DVD Studio Pro 4.1.2 create build files and discs that
are more reliable than those created with previous releases. If possible, it is strongly
recommended that you open any HD projects from previous DVD Studio Pro releases
and use the DVD Studio Pro 4.1.2 build and format functions to re-create the build files
and discs.
Note: Choose the Delete option if you see a dialog about whether to reuse or delete
the existing HVDVD_TS folders and their files. Do not choose Reuse. This ensures that a
complete new set of files is created.
HD Projects Burned to Red Laser Discs Now Work More Reliably
HD DVD projects that you burn to a red laser disc will now play more reliably in HD
DVD players.
Some HD DVD Players Fail When Switching From Interlaced to Progressive Video
HD projects that allow the viewer to jump from an element using interlaced video to
an element using progressive video may have issues when played back on some set-
top HD DVD players. It is expected that future firmware upgrades to those HD DVD
players will address this issue.
Some HD DVD Players Incorrectly Position Button Highlights
Some HD DVD players incorrectly position button highlights when they are placed over
720p or 1440i backgrounds. Button highlights placed over 480i, 480p, and 1080i
backgrounds are correctly positioned.
