We have all the tools in Python to do this, we only need to glue them 
together!

NSMovie has a QTMovie method which returns the quicktime movie object. 
If we have a way to pass this to Carbon.Qt.Movie() we would be all set.

And note that the same goes for lots of other objects for other 
frameworks that Cocoa can wrap. This is an area in which Python can 
really outshine Java, because we not only have the Cocoa interface but 
also the Carbon and other toolboxes.

My preferred way to glue this together would be to add a method 
pyObjC_NSMovieAsMovie to PyObjC, which would return the void* as a 
Carbon.Qt.Movie object (and also the reverse: initWithMovie: should 
accept a Carbon. Qt.Movie object too. Note that this will not tie 
PyObjC to the Carbon.Qt module directly: the MovieObj_New() and 
MovieObj_Convert() routines (which convert C pointers from/to Python 
objects) are in the Python core, and when first invoked they will 
attempt to load the required module. After that the calls are fairly 
cheap: one extra subroutine call.

Or we could say that NSMovie and initWithMovie: are pretty useless as 
they are anyway, and just let those always use Carbon.Qt.Movie objects.
