Apple DVD Studio Pro 4 - Manual (Page 415)

Previewing Angles
If you are previewing a mixed-angle track and select a video stream other than V1, the
preview still plays the V1 stream whenever the selected video stream is not present.
To see the multi-angle or mixed-angle stream actually function, you need to use the
DVD Studio Pro Simulator.
Simulating a Track
Simulating a track allows you to verify all streams and any special interactivity you may
have built into it.
To simulate a track
Do one of the following:
µ
Select the track, then choose File > Simulate Track, or press Command-Option-0 (zero).
µ
Control-click the track’s name in the Outline tab or its tile in the Graphical tab, then choose
Simulate Track from the shortcut menu.
µ
Control-click one of the streams in the Track Editor, then choose Simulate from Track
from the shortcut menu.
These methods force the Simulator to start at this specific track instead of the First Play
connection, as it does when you open it using the icon in the toolbar.
Once the track starts playing, you can use the Simulator’s controls to choose the streams
to view (angle, audio, and subtitle).
See Simulating Your Project for information on using the Simulator.
