Well, it would seem it is not a beta anymore.

Now for the bad news...
It seems that certain sites built in earlier versions of flash(5, 6, 7, 8) are NOT displaying in flash9 player.
If the player request (in the object tag) is changed from your current version request(for example, on my site it was 6,0,76,0), to 9,0,16,0 then, and only then will your flash site/movie be displayed.
I had to change mine, even though it was built with a much earlier version, in order to be displayed.
