Open an MP3 (or any other audio file) in QuickTime Pro. Select File->Export from the menu. Select 'Movie to OGG' from the export options combo. Select 'options' next to the combo. A dialog will pop-up. Select options in the audio field. Nothing happens. I am stuck with 'default' export parameters which seems to be set at the highest quality export.
