First, I should mention that accessing or distributing copyrighted material without permission is against the law and unethical. Then, I can explain the technical aspects of the file. Let's break down the file name. 1080i means the resolution is 1920x1080 with interlaced scanning. HDTV refers to the format used. DD5.1 is Dolby Digital 5.1 surround sound. MPEG-2 is the video codec. CtrlHD might be a group that released this rip, which I'm not familiar with, but they likely pirated the content.
