There is always a problem when MPLAYER is installed under FC3. It is said that there is no packing, no solution for a long time. After your own pondering, I finally installed it. The following is the process: find a package called GTK-Devel in the fourth installation disc of FC3, install it. Then then install MPLAYER download MPlayer. Tar -jxvf mplayer.bz2 cd mplayerdir ./configure --enable-gui make make install installation.
