mystictim, /etc/gnome/defaults.list is meant as a read-only file where the GNOME default mimetypes are listed. You shouldn't modify it. Your method is an intrusive workaround and is not acceptable as a way of customizing what's choosable in the Media tab of the Nautilus preferences.
As far as I can tell, what determines the options in that tab is the mimetypes that applications report they are capable of handling in their .desktop files. I filed bug 209107 about VLC not registering the correct mimetype. -- Hardy: gconf-editor changed settings ignored by system https://bugs.launchpad.net/bugs/203877 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
