[MacRuby-devel] Help with QT syntax

I've been going through the MyRecorder example in the QTKit Capture Programming Guide (which works fine) but am having problems with the MacRuby syntax for the following: - (void)captureOutput:(QTCaptureFileOutput *)captureOutput didFinishRecordingToOutputFileAtURL:(NSURL *)outputFileURL forConnections:(NSArray *)connections dueToError:(NSError *)error I'd be very grateful if someone could point me in the right direction. Thanks
