well i just boguht a movie and im trying to back it up on my hdd and go into dvd 2 xbox it starts backing it and everythings going great and then with about 75 percent of the movie left it says its done copying it and 0 files failed

so i go into file manager and i look at what i copyed it copyed all of the dvd extras and none of the movie, its so weird. the movie im trying to backup is fantastic 4 and it wont copy the movie
