This init solves the following problem (only occurs on Power PC macs).
If a native application was built using QuickTime 1.6.2 headers and the application called MCGetMovieExtended or MCGetMovie (which translated into MCGetMovieExtended), the native application will not run with QuickTime 2.0. (MCGetMovieExtended was renamed MCGetIndMovie to reflect functionality.) If the PowerPC application is run with QuickTime 1.6.2 everything works. If the PowerPC application is run with QuickTime 2.0 the application crashes in a "spurious interrupt".
If an application has not shipped yet, and they must have this call, they should use QuickTime 2.0 and require QuickTime 2.0 with their product (2.0 fixes a lot of problems with 1.6.2).
If an application has already shipped for 1.6.2 using this call, the application will refuse to run with 2.0 installed. The enclosed init checks for QuickTime 2.0 final and QuickTime 2.0 PowerPlug and then updates the QuickTime shared library to include glue for MCGetMovieExtended. The application should now run.
To use the init:
Drag the file to the extensions folder. It must come after "QuickTime¬" and "QuickTime¬ PowerPlug" alphabetically. If there are no name changes "QuickTime¬ PowerPlug Fix" will work fine.
