I have this litle issue, I'm recently update my distro to Fedora 12, then install mplayer and the drag'n drop functionality doesn't work, even with the svn source, I have no idea what can be the problem, but this happend with nautilus and dolphin, don't append with thunar. I'm using fedora 12 x86_64, gnome 2.28 and MPlayer SVN-r31054-snapshot-4.4.3 (C) 2000-2010 PD: sorry for my bad english
