Apple strives to provide maximum reliability for its customers. This update provides specific improvements that many Apple Macintosh customers will find helpful.
What is the Apple Multimedia Tuner?
The Apple Multimedia Tuner system extension includes a set of software enhancements that improve the performance and reliability of some software applications and multimedia titles that utilize Apple's QuickTime and Sound Manager software on Macintosh computers running system software versions 6.0.7, 7.0, 7.0.1, 7.1, 7.1.1 (System 7 Pro), 7.1.2 (for Power Macintosh), or 7.5.
What are the enhancements that the Apple Multimedia Tuner 2.0.1 provides?
Prior versions of the Apple Multimedia Tuner may not have been active running pre-System 7.1 versions of the system software. This problem has been fixed in version 2.0.1.
Multimedia data read from ISO 9660-only CD-ROM discs may not have been displayed properly when earlier versions of the Apple Multimedia Tuner were installed. This problem has been fixed in version 2.0.1.
Users of Adobe Premiere™ and other multimedia authoring software programs will experience improved system reliability under low-memory conditions with version 2.0.1 of the Apple Multimedia Tuner.
The following enhancements were originally incorporated into version 2.0 of the Apple Multimedia Tuner and are also included in version 2.0.1:
QuickTime 2.0 contains enhancements that can dramatically improve QuickTime movie playback performance in software applications and multimedia titles. Some existing software applications and multimedia titles do not properly initiate movie playback and will not be able to realize the performance improvements of QuickTime 2.0. The Apple Multimedia Tuner 2.0.1 helps these applications and multimedia titles achieve much smoother and consistent movie playback.
In some situations, there may not be sufficient RAM available to play sounds. If you are using Sound Manager 3.0, the Apple Multimedia Tuner 2.0.1 will improve the system's ability to play sounds under these conditions.
The Apple Multimedia Tuner 2.0.1 improves the reliability of Quadra 660AV and Quadra 840AV systems running some compute-intensive applications under low-memory conditions.
How do I know if I should use the Apple Multimedia Tuner?
This system extension should be used with QuickTime 2.0 and with the Sound Manager 3.0.
The Apple Multimedia Tuner automatically determines whether your computer can benefit from the enhancements it provides. If so, the Apple Multimedia Tuner initializes itself when your computer starts up, and its icon displays briefly at the bottom of your screen. If not, the Apple Multimedia Tuner has no effect, and its icon is not displayed during start-up.
The enhancements provided by the Apple Multimedia Tuner 2.0.1 will be incorporated into future versions of QuickTime and the Sound Manager.
Installing the Apple Multimedia Tuner:
To install the Apple Multimedia Tuner, simply drag the Apple Multimedia Tuner system extension to the Extensions folder inside your System Folder, under System 7, or to the System Folder, under System 6. You must restart (reboot) your Macintosh to take advantage of this software.
