This file contains 12 minutes of advertisement after the movie.

Removing it could result in a 1/4 AFR. Going to try it...
EDIT:
This is definitely NOT a DVD rip! The fps is weird and the first few lines at the top are shifted slightly to the left during the whole movie. It looks like recorded to a VHS tape from TV and ripped from the tape afterwards. The commercials advertise TV programs coming up next on the SHOWTIME channel (http://www.sho.com/site/homepage/index.do). I had a look into it and it's not a horror movie! It's a sci-fi/action flick.please -> non-horror section for being a sci-fi/action movie (what to do about the fact that it's not a DVDrip but a TVrip???)
