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 be
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.
