Monsters University

Monsters University DVD would fail on lsdvd scanning it. I dug around and found out that when libdvdread scans the IFO, it skips over some of the program chain variables if it can't access it. Applied a patch to lsdvd upstream's git repo, and it'll be present in the 0.17 release when it comes out. Also fixed dvd_info so that it'll also check for the same problem, and work around it. That'll also be included when it sees a 1.0 release.
