This must be a problem at their end, I don't use iPlayer that often but when I loaded it up in both Chrome and Firefox I'm experiencing similar issues.
Firebug seems to illustrate that part of the page is loading and certain separate HTTP requests are returning internal server errors meaning the Javascript that loads the Flash container is never run. I don't know why it would always work in IE, perhaps you've just been lucky. Have you tried refreshing the page multiple times in Firefox to see if it eventually loads? I occasionally get the video loading but the stylesheet failing to load giving my unstyled output but the video plays.
The BBC should really know better than to load a lot of separate files on a traffic heavy site generating loads of HTTP requests. See the images below for Firebug and Chrome Developer tools results:
(Iceweasel is Firefox, just rebranded), you can see that some of the external Javascript is failing to load.
