1. I have a DivX video 2. The audio is *drumroll* the infamous MP3-encoded DivX audio 3. The audio does not play in QT6 10.2.1 with the DivX codec alpha 3 installed, but the video does 4. Running the file through the DivX validator produces a completely worthless file: no audio, no video, and smaller by 25 MB (about 3%) 5. The file plays perfectly fine on my PC Assistance required.
