Apple DVD Studio Pro 4 - Manual (Page 612)

• & (and): Provides a binary bit-wise “and” function. Several of the elements contain
multiple settings. You can use the “and” relationship to extract one setting from the
element. For example, if you choose the Audio Player Config element (which contains
several settings related to the DVD player’s audio capabilities), a state of 2048-DTS, and
the “and” relationship, you can only play the track if bit 11 of the 16-bit byte is one,
indicating that the DVD player supports DTS audio. See
Using Bit-Wise Operations for
details on using a bit-wise “and” function.
Issues with Display Conditions
There are several issues with using display conditions that you should be aware of:
• The Last Chapter Played setting is reliable only when assigned to menus: When using the
Last Chapter Played setting for display conditions assigned to a track or story, you get
unreliable playback on some DVD players. The Last Chapter Played setting can be used
reliably with display conditions assigned to menus.
• Display Conditions using the subtitle stream number only work with the subtitle stream set
to View: When you configure a display condition for a track or story that uses the subtitle
stream number option, the display condition works correctly only if the subtitle stream
is set to be viewed. For example, if you configure a menu’s button to use subtitle stream
S1 and a track has a display condition configured for subtitle stream S1, the display
condition only works correctly if you also select the subtitle stream’s View checkbox in
the Button Inspector.
• Some DVD players do not allow parental level in display conditions: Some DVD players
do not process the parental level option correctly when used in a display condition,
allowing content to play that should be disallowed.
Important: DVD players always set SPRM 13 to Not Rated when playing DVDs authored
with DVD Studio Pro.
Remote Control Settings
An important part of authoring a DVD title is to assign functions to the DVD player’s
remote control buttons. For most projects, you set these functions for the entire disc.
However, you can override several of the disc settings for individual tracks, stories, markers,
slideshows, and menus.
If an individual element has more than one remote control setting:
• Track, slideshow, story, and menu settings take precedence over disc settings while
they play.
• Marker settings override all other settings while that part of the track or story plays.
Note: All of these settings can also all be made in the Connections tab.
