The identified file type is not determined only by the extension as you would find out, and as Leon said above. In *nix systems file types are NOT identified only by the extension as they are in the windows world and this warning is telling you the file type is not properly designated by the extension. Wmv video and asf video are two entirely different animals handled by different codecs and can have different risks associated. > -- > Leon >
