I can't view DivX Web player videos on my Firefox web browser. I was told that I had to install mplayer and mplayer plugin for Mozilla to be able to play these videos.

I installed these from yast but it still doesn't play. I know where mplayer is installed but where is the mplayer plugin installed?

it's not in the directory
/usr/lib/mozilla/plugins/

nor is it in

/usr/lib/firefox/

Thanks
