NSMovie playback cutout

Hi,

I've tried directing this question to the Quicktime API mailing list a few times with no luck.

The first Cocoa app I wrote was a simple app for a DJ friend of mine. It plays multiple audio files and lets him cross fade b/w them. I use an NSMovie instance for each file I'm playing.

Before installing Jaguar the software worked. Now when I start playing a new file the other files tend to stop. They can be restarted but this in turn causes other files to stop. Also, when I display the file dialog to select new files to add to the playlist the audio pauses and doesn't restart until I dismiss the dialog box.

I suspect there has been a change in a default setting in the Quicktime API. In the QuickTime Player app preferences there is a checkbox to select 'Play sound in frontmost player only'. There's probably a Quicktime API function to toggle this setting for a movie. I've spent a long time reading the Quicktime 6 API reference which I downloaded as a PDF from the Apple web site. I can't find any functions that hint at setting something like this for a movie.

To eliminate the possibility that my own bogus code is to blame I've written a very simple test app that just allocates two NSMovies and tries playing them at the same. The same thing happens. One or other always cuts out after a few seconds.

Has anybody had a similar problem ? This is really frustrating.
