Using QTSRC with the EMBED Tag

The advantage in using the QTSRC attribute in the EMBED tag is that you can essentially "fool" the browser into handing the URL to the QuickTime plugin because as far as the browser knows, the SRC attribute is calling for a media type that only the QuickTime plugin is registered to handle.

For those rare cases where the person has a version prior to QuickTime 4, they will see the SRC file which instructs them to download QuickTime
This is actually an .mp3 being played by the QuickTime plugin. The SRC attribute is required for the browser, but can be ignored by the plugin provided a QTSRC attribute is included.
