Can't find the Quicktime plugin Javascript methods

Question

I am generating Quicktime embed code dynamically (using
QTGenerateOBJECTTextXHTML), with EnableJavaScript = true,
and inserting in the DOM.
The movie loads and plays back fine. I want to use Javascript methods
like Play(), GetMovieTimeScale(), etc. to control it.
I used to do this a couple of years ago and all I had to do was:
var movie = document['mymovie'];
movie.Play(); // etc.
Now when I access the plugin element (either object or embed), it
does not seem to have any of the Javascript methods.
Here's how I'm accessing the plugin object (it now varies between browsers):
In Safari:
document['mymovie'] returns an HTMLEmbedElement
document.getElementById('mymovie') returns HTMLObjectElement.
Neither one of them seems to have the Javscript methods.
In Firefox,
document['mymovie'] returns an array: [object#mymovie embed#mymovie]
document.getElementById('mymovie') returns object#mymovie
Again, neither one of them seems to have the Javscript methods.
I see the same behavior in Chrome and Opera, so I must not be looking
in the right place for the methods.
I searched these archives and the web and found hardly any recent
discussion of Quicktime Javascript scripting.
Thanks in advance for your help.

Oops, I should have used code formatting for these:
var movie = document'mymovie';
object#mymovie, embed#mymovie
