Catch up movies not full length

<p>Recently downloaded a movie, The Changeling, for the third time, and the length is only 56 minutes, and it is supposed to be 136 minutes long. We have also tried to watch the same movie on other devices through Dstv Now, but the movie still is 56 minutes. Tried to download SD as well as HD but to no avail. Can this be resolved?? </p>
