I installed the java plug-in and I did everything it said about how to configure it and it says "Java player installed, you must restart Mozilla for it to work"... so I restart it and nothing happen's......................... My second problem is that I am trying to install MPlayer and I downloaded "mplayer-1.0pre8-0.20050820.1.i386.rpm", opened up an installer program and it appeared to have installed but nothing happened... I also downloaded "lame-3.96.1-2.1.fc3.fr.i386.rpm" and "player-1.0pre7-1.i386.rpm.... They all went through this self installer thing but nothing happened... Help?

what do you want to happen?
to launch mplayer do a whereis mplayer. It will prob be in /usr (i think /usr/share/mplayer for fedora) to launch it type the full location. in run cmd

/usr/share/mplayer
and it should launch. Same idea with the others

Here are some instructions for mplayer

Alright, I installed MPlayer and all of that good stuff but I dont see it anywhere and when I write "mplayer" in terminal to get it to work it just says the following

Mplayer needs a file to launch... It does not just open like a tipical GUI app...

I kind of figured that whatever that meant was important but I have no idea where to go with it

oh wait i get it, thank you very much sir

First determine what file you want to run be-it-an .mp3 .mpg. etc... Say you want to launch a file in your home directory under music called ToofDogger.mpg then:

mplayer ~/music/ToofDogger.mpg
or
mplayer /$HOME/music/ToofDogger.mpg
