      4. Make sure there are no background tasks, like copying files in the Finder, that could make the computer busy
    You can use the Software Update control panel to install Mac OS 9 Update and Apple DVD Player 2.2. They can also be download from Apple Software Updates at http://www.apple.com/swupdates/ . Use the QuickTime Updater application in the QuickTime folder to update to QuickTime 4.1.1 or later.
