Adobe Flash Media Playback
In case you didn’t notice, Adobe has released the free Flash Media Playback which makes it easy to include flash video on your website.
You can either use the player hosted by Adobe
or download the player to your website.
Among the many features built-in to the player, I found the AutoLoop and the poster frame very handy and they can simply be set by HTML embed tags.
Give it a try. It may save you from hours if not more of your work.
