<p>I'm trying to convert old QuickTime framework code to the 64-bit Cocoa-based QTKit on OS X, which means that I can't drop down to the straight C function calls at any time.  Specifically, I'm trying to find a way to write QuickTime VR movies with QTKit, as they require some special metadata to set the display controller.  How can I do this with QTKit?</p>
