As stated above, you need a couple of steps added to your Publishing and HTML.
1) Your HTML says you expect the player version to be v6, yet you created it
with Flash 8. Your HTML code is likely not that generated by Flash 8
publisher, because it will detect the minimum level of version needed to play
the content. It appears your video uses an alpha channel so you need to stay
with F8.
2) And, your code does not detect any version of Player plug-in. So your
users won't see what you want if their browser isn't updated.
Suggestions:
a) You likely need to change some Publish Settings in F8 with your FLA
document:
Click on File/Publish Settings, then select the Formats tab and place a check
in the HTML box. Then go to the HTML tab and place a check in the Detect Flash
Version box. Now when you publish the video, it will create the HTML needed to
check for v8. You need to provide appropriate alternate content and a friendly
message in the HTML to tell viewers to upgrade, etc. Read the code and you
will see where to place this.
b) Here is a link to a flash detection scheme I feel is better than the
default scheme provided with F8:

Goodl luck.
