Q: QuickTime VR Panorama doesn't play correctly from a webpage

http://www.nps.gov/features/glac/gallery/082105b.htm is supposed to play a QuickTime VR Panorama (082105suelake.mov).  It contains the following <embed> tags:

<embed src="../video/panoramas/082105suelake.mov" width="600" height="465" autoplay="true" controller="true"></embed>

To play it, all you do is drag your clicked mouse across the image and it's supposed to play as long as your mouse is clicked.

That worked through Snow Leopard (Safari 5.1.10, etc.).

But with Lion and Mountain Lion (Safari 6.1.1, Firefox 27.0, and Google Chrome 32.0.1700.107, and earlier verisions), instead of moving with the clicked mouse, it would jump to what should have been its final position when the mouse was released.

Safari 7.0.1 correctly plays it (one of the reasons I upgraded from Lion to Mavericks), but sadly, Firefox 27.0 and

Google Chrome 32.0.1700.107 both behave on Mavericks as they did on Lion.

All three use QuickTime Plug-in 7.7.3 to play it; so, I figure Safari 7.0.1 must be providing some <embed> parameter values that Firefox and Chrome don't know about.

The standalone QuickTime Player 7  plays the panorama fine.  It shows the following Properties:

everything else is either blank or the default values.  The Inspector display shows

with the Video Track unchecked, and

with it checked.  I can only imagine what happens on Windows (Internet Explorer, etc).

If you install the DivX Web Player (divx.com), DivX Web Player version 3.1.0.13 — from file “DivX Web Player.plugin” takes precedence over QuickTime Plug-in 7.7.3, when playing .mov files in Safari (doesn't get installed by default in Firefox or Chrome).

To get around that, I added type="video/quicktime" to the <embed> parameters, in http://home.comcast.net/~mybrandt/082105b.htm, hoping it would fix the problem Firefox and Chrome were having.  A similar fix made Safari choose QuickTime over DivX, when playing a QuickTime movie.

But instead of playing it, like it did without DivX installed, with type="video/quicktime" added, Safari 7.0.1 now shows

where the panorama image should be.  And, adding to my frustration, the extra parameter had no effect on Firefox or Chrome.

All are using QuickTime Plug-in 7.7.3, but don't behave the same — making this problem beyond my level of comprehension.

So, what are the necessary <embed>, or <object>, or QT_WriteOBJECT_HTML, or QT_WriteOBJECT_XHTML parameters for a QuickTime VR Panorama?

I can find all sorts of documents about QuickTime movies, but not that.  Maybe I'm just looking in the wrong spot.  But I've sort of run out of time.  If someone could provide a template to use, it would be most appreciated.
