Okay I'm confused. How do I set the attributes when I init and
initWithURL at the same time. I can't seem to find a method to do both.
The problem is that when I first init withURL and then use setAttribute,
it doesn't take. I check right away and the value is set YES rather than NO.
Use initWithAttributes:error:, and along with
QTMovieRateChangesPreservePitchAttribute, use QTMovieURLAttribute.

One important aspect of my app is teh ability to speed and slow
audio (and video playback). On the old NSMovieview this worked like an
analog tape machine: if you used NSMovieview setRate: it would slow the
sound down smoothly but make it lower; which is fine. Under the new
regime, the audio playback using [[QTMovieview movie] setRate: (float)]
you get VERY choppy sound and no variation in tone. I don't actually
care about the variation in tone, I care a lot about the smoothness of
the sound. Is there any way to get smooth audio while changing the rate
to r != 1?
Maybe you could try setting QTMovieRateChangesPreservePitchAttribute
to NO when you initialize the QTMovie.
