If I embed a quicktime file using the appropriate code, the file starts loading but it never starts playing.

Code:
<object classid='clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B' width="533"
        height="339" codebase='http://www.apple.com/qtactivex/qtplugin.cab'>
      <param name='src' value="http://www.daretobefabulous.com/henrivideo/img/Henri%20Laborde%20b%20day%205.31.11.mov">
          <param name='autoplay' value="true">
          <param name='controller' value="true">
          <param name='loop' value="true">
          <embed src="http://www.daretobefabulous.com/henrivideo/img/Henri%20Laborde%20b%20day%205.31.11.mov" width="533" height="339" autoplay="false"
        controller="true" loop="true" pluginspage='http://www.apple.com/quicktime/download/'> </embed>
        </object>
Now size might be an issue, but if on the other hand I link directly to the file itself, it's starts playing (streaming) without a problem. Same file, same size.

Any ideas on why this is so and what to do about it? Thanks.
