Hello,
First of all i would like to say thank you to all the moderators and those who anwser questions for free, i think it is time that someone actually recognized it, ive used this forum a lot of times always finding the anwser to my problem but now is the time for me to make my first post, ok here it goes

I am a running under FC3 i just compiled mplayer with gui, and downloaded skins & codecs and installed them in their respective directories, ive tried a lot of different places for the skins that i read but nothing seems to make the gmplayer work, so here goes the error and my system specs


This iis the first error message i received

then i mv the skin to another directory and it gave me this

Were is the first error?

Anyway here are some good instructions:

updated for 1.0pre6

The error is the gui never opens!! :@

To run gmplayer correctly, you need to install just one skin(ONLY ONE) at "/usr/local/share/mplayer/Skin/default/" (If some folder is missing you need to create it). This will be the default skin for Mplayer, if you want to have others, install them in your home folder.

Actually i have more than 10 Skins in /usr/local/share/mplayer/Skin directory and everything works file.
All you need is to link one of the skins to default
