File fails because it expect an MP4 header with type "M4A" but the file actually contains "m4a". Changing it with a hex editor fixes it.

Technically Apple says its supposed to be lower case, but other software I've tried doesn't seem to care, so I fixed it in r27805.

Edit: Flipped the cases around in the SVN commit message. Uppercase is correct, lower is less so.
