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.

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?
