The problem is that it isn't an MPEG file, its a Quicktime file. You'd 
have to convert it in some process as described on the Sizzle web page 
- probably running it through MediaPipe. In my experience, MediaPipe is 
pretty crashy on encoding though. You might be able to demux the QT 
file using MediaPipe, then encode it with ffMpeg from some intermediate 
audio and video formats.
