Basically I think valid HTML 4 would have to look like this:
<object type="video/quicktime" data="media/movie.mov" width="400" height="300">
<param name="src" value="media/movie.mov">
<param name="controller" value="true">
<param name="cache" value="true">
<param name="autoplay" value="true">
<param name="loop" value="true">
<param name="pluginspage" value="http://www.apple.com/quicktime/download/">
<p>Hey, no QT installed!</p>
</object>
I can't test it here, because installation of QuickTime tends to mess up too many settings on my PC.
The most reliable result is achieved by using <embed>, which has been deprecated by W3C in their eternal wisdom. So the choice is between valid HTML and maximum audience...
