Normally, Apple DVD Player will play DVD content only from a DVD-Video disc. However, Apple DVD Player 2.3 and later can play DVD-formatted content from another source.
To enable playback from other sources:
1. Choose Preferences from the Edit menu.
2. Click the Advanced Controls tab.
3. Click the "Add 'Open VIDEO_TS' menu item to File Menu" checkbox to enable that option.
Figure 1 DVD Player prefs window
You can now (when playback is stopped) select a DVD-formatted VIDEO_TS directory using the Open command in the File menu.
Figure 2 Open VIDEO_TS menu window
Do not open the VIDEO_TS folder, but use this command to choose a VIDEO_TS folder that contains files that are in the DVD standard layout and format.
Figure 3 Select a VIDEO_TS folder window
Note: You cannot play DVD content from a server volume.
After you've selected a source folder, the player will ignore any DVD-Video discs on the desktop. To play from a disc, click Eject, or use the Open command to select the VIDEO_TS folder on the disc you want to play.
