Let's go though some of the information in the embed tag:
WIDTH and HEIGHT:
These values (numbers) tell the browser the width and height of your movie.
You can get this information after you export your iMovie to QuickTime.
Double click your QuickTime movie icon for your movie and it will open in the QuickTime Player.
From the File Menu, Go to -->Movie --> get Movie Properties.
With Movie showing in the left Menu, click on the Right menu and select size.
CODEBASE:
This web address gives Internet Explorer information about QuickTime.
PARAM:
This is the paremeter of the object. It has a name and a value.
SRC is the URL that points to your movie file - the web address, directory and file name.
AUTOPLAY tells the browser whether to automatically play the movie after it has loaded.
(TRUE means it will play, FALSE means it won't start playing).
A sample of a QuickTime movie with the autoplay set to "TRUE" is the little movie that plays on my iMovie web page at:

CONTROLLER tells the browser whether or not to display the QuickTime controller beneath the movie.
FALSE means that no controller is available. TRUE displays the controller. If the controller does not display fully you can add 15-20 pixels to the WIDTH and HEIGHT values to fix the problem.
EMBED:
This is the tag that points to your movie file. It includes the same attributes as the PARAM. If you have only this tag your movie will not display correctly in the current versions of Internet Explorer.
PLUGINSPACE
This is a pointer to the download page for QuickTime if the browser doesn't have the QuickTime plug-in.
Easy! Scared to "embed"? ... Just make a link
Cut and paste HTML code ... Without the controller - autostart
Cut and paste HTML code ... With the controller - Autoplay and click to play.
