I am having an issue that I need some help with. I recently convinced my girlfriend to switch from Windows Vista to Fedora Linux

. So far the conversion has been painless & I have her doing in Fedora the same things she used to do in Vista with one exception. My girlfriend likes to go to
http://tnt.tv/ and watch the online episodes. Since switching over to Fedora 11, she has been unable to watch any of the episodes online. This poses a problem for me because I can't get it to work. I have the computer where it will play everything else, but the media streamed by this site. So, I am asking for some help. Any ideas?
