Exporting a movie

Hi, I've been successfully exporting a movie my application is constructing. But as with all movie exports, it takes some time. As such I was wanting to display a progress bar.

I found - (BOOL)movie:(QTMovie *)movie shouldContinueOperation: (NSString *)op withPhase:(QTMovieOperationPhase)phase atPercent: (NSNumber *)percent withAttributes:(NSDictionary *)attributes in the docs.

And promptly started implementing it in my delegate. The method gives me back percentage complete as it should. What I'm having problems with though is the phase... I expected to get back one call as it started with QTMovieOperationBeginPhase, then a whole load with QTMovieOperationUpdatePercentPhase, and then one with QTMovieOperationEndPhase as it completed. But what I get instead is lots and lots and lots of QTMovieOperationEndPhases.

What's up?

Bob
