mplayer plugin on Firefox
 

Ok I've Installed mplayer on my PC and I've also downloaded the rpm for the mplayer plugin and I installed it (rpm -ivh mplayerxxxx.rpm). I went to the mozilla plugin FAQ and saw that I have to put mplayerplug-in.so in the plugins folder of FireFox. SO Isearched for the mplayerplug-in.so but theres only two files installed on my Box (mplayerplug-in.config and mplayerplug-in.types) so I tough that just copying the file mplayerplug-in.types into the firefox plugins directory and I opened firefox and tried to see some movie trailers from the apple website and it said I needed the plugin. How I resolve that???
-Thanks
