Whenever I double click on a .mp4 video file in nautilus the following warning message is displayed: "The filename "test.mp4" indicates that this file is of type "mp4 document". The contents of the file indicate that the file is of type "MPEG-4 video". If you open this file, the file might present a security risk to your system. Do not open the file unless you created the file yourself, or received the file from a trusted source. To open the file, rename the file to the correct extension for "MPEG-4 video", then open the file normally. Alternatively, use the Open With menu to choose a specific application for the file. " Now as far as I know, .mp4 is the correct extension for MPEG4 video files (I've never heard of a .mp4 document file), so how can I get nautilus to open the file rather than displaying the warning message? Using the "open with" command works fine, but it's annoying to have to do that every time. _______________________________________________ gnome-list mailing list gnome-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gnome-list
