Answer:
1) Peter requires at least version 1.5 of QuickTime to run (QuickTime is
an extension that plays the movies found on Peter & Santa Claus). The
Peter & Santa Claus CD comes with QuickTime 1.6.1. To install it, drag
it to your System Folder (press OK when your Macintosh asks if it
should put QuickTime into the Extensions folder), and restart your
computer.
2) If you already have QuickTime installed on your computer, perhaps the
extensions were not loaded on start-up. Try restarting your Macintosh.
If this still does not work, check the version of QuickTime that you
are using by selecting it and choosing "Get Info" from the File Menu.
