Ok, my continuing saga with sound and mplayer. I installed via freshrpms a version of mplayer, but it did not have the codecs required, so I then downloaded the src code from mplayerhq. I also downloaded the skins, codecs, and then installed all of the missing development libraries that showed up when running the configure script. This allowed me to finally run make and make install to get mplayer mostly working. I can playback either windows media or quicktime movies that I download from United Streaming from the command line , but, I can't launch the gui interface, even though I included the option to compile it. I have tried to troubleshoot using <a href="http://www.mjmwired.net/resources/mplayer-fedora.html">http://www.mjmwired.net/resources/mplayer-fedora.html</a> The error message is below: Has someone that has manually compiled seen this issue? Also, how do I add mplayer to the menu system (we are using gnome)? The menu entry is removed when I uninstall the version that I installed via yum. If no one has seen this, then I will follow the suggestions below and generate the debug info.
