video on BBC website not working with Firefox

I have the latest version of flash installed, but the BBC's new video
format only works with Safari. I get a "this content isn't available at
the moment" when using Firefox. (No problems with iplayer though.)

Does anyone have it working with Firefox? (I'm on 10.4.11 intel)
