Mplayer and xine

[KIMARIO FAWKES]

Hey guy i installed mplayer and xine, they dont work at all i followed  some 
instructions off of Fedora Core 3 Tips and Tricks;

1. i can't get any plugin into work is there a good mirror to downoad xmms?
2. all of the music applic recognize my dvd and dvd burner, but does not 
play nor do i get any sound it just runs...  did a check cdrecord  status 
and it said every thing was fine what could be the problem?
