Some flash files don't appear on macintosh

I've installed the latest flash player on a macintosh 10.4.11. But I've noticed that a few flash sites don't appear. Among them the flash player page itself: http://www.adobe.com/products/flashplayer

As you can see, where the flash movie should play there's just white space. Both on Safari and Firefox for Mac.

I've also tried in on another mac so it's not just my computer.
I've checked the version on: http://www.adobe.com/software/flash/about and that flash movie runs fine. It also says: 'You have version 10,0,32,18 installed'

At home on a pc these pages (like http://www.adobe.com/products/flashplayer) work fine. What kind of thing could make the swf disappear on a mac?

Request for all mac users: can you open the flash player page
http://www.adobe.com/products/flashplayer

And check whether the sample movie runs or fails?

If you only get the play/pauze buttons, but the movie itself is just white space (just like my preview image), could you write down you mac's specs?

Works fine on my G4 running OSX 5.7, Flash Player 10,0,22,87 installed. Might be worth reinstalling the player. Can't think why otherwise.
