I noticed this problem when a friend of mine directed me to a site with an
embedded movie object:

There are a few issues here:
1. If I look at this site in IE7, it shows up with a red "x" icon for the
reserved object dimensions
2. If I look at this in Firefox 2, it doesn't show up at all - in fact, this
is where we found the problem
3. Checking this in Opera 9, the movie appears correctly
4. My friend sent me the link to the actual youtube page with the movie - I
can see it just fine in all 3 browsers on that page

5. If I view the source and navigate to the link in any of the browsers, I'm
able to see the movie
6. I've tried uninstalling and reinstalling all of my browsers and Flash and
still the same results

Has anyone ever seen anything like this? I'm shocked (but not amazed) that
this kind of thing would even happen in Windows XP.
