aspect ratio issue with mplayer and XFCE 4.-3.99.1

[Ferréol de Soras]

Hello,

I am having a little trouble with XFCE and mplayer (& Xine && VLC).

It does not "lock" mplayer and others window aspect ratio even with xv 
output.

XFCE3 and Gnome 2.2 do.


-did anyone experienced this issue ?

-did anyone found a solution ?

Thanks for any help that could come.

(Aplogises if this problem is already too known....)
