Wait, sometimes in movie file names, people use certain letters to denote resolution, source, or group. For example, "DVD-Rip" is a common term for a movie ripped from a DVD, and then maybe "xvid.ac" could be a site or a codec. So the user might be referring to an extended version of "El Patriota" (which I think is "The Patriot") in DVD rip XVID AC format, and they want to know what makes the extended version better.
