 I'm running ffprobe on an ISO file which contains 2 titles (one for 59
 seconds, and another 1 min). But ffprobe shows a duration of 1 min, which
 is the duration of only one title.

 the ISO file I used is here
 https://dl.dropboxusercontent.com/u/89678527/2videos.iso

 Below is the output of ffprobe
