Is there a problem with the Mac authoring tool that prevents conversion of source media to AAC format?
Conversion settings for Vorbis and PCM are not an issue, but AAC consistently fails with every source media I throw at it...
21:45:49 - 'AAC' reported 'AAC bit stream error' for 'any_old_audio.wav'
