Mplayer, aiuto

[Bulfio]

Ciao a tutti,
ho un problema con mplayer: lo installo da root, con la GUI, e quando lo faccio partire, sempre da root, non mi da alcun problema, ma quando lo faccio partire da utente normale, mi dà i seguenti errori:

Skin not found ( default ).

Non riesco proprio a capire, mi dice skin non trovata, ma andando a vedere nella destinazione che mi dà, la cartella c'è... e poi se apro un terminale come root e faccio partire il programma, questo va senza problemi...!!!
Sono disperato, perchè la cosa mi pare assurda!!!

Accetto qualsiasi consiglio!
Grazie mille!!
Ciao!
