There is a _huge_ amount of content on the web that uses MPEG-4, which
QuickTime supports (note that on Windows DirectShow doesn't support
MPEG-4 out of the box, and AFAIK only supports MPEG-1 and WMV (for

the QuickTime container format (.mov), even if the content is MPEG-4
(whose own container is based on the QT one).
