Using shrink to re-author and backup this dvd as 'movie only'. Seeing that two title sets come up. In the main window they each read at slightly different sizes (5516 & 5696 Mb), so they appear to be two different sets. However, nothing on the main menu offers a selection between the 'two' sets, and there is no second 'angle' offered when playing on a standalone. A bit confused as to what the difference is here between them... I can just choose one or the other, but it is interesting to see two titles and no distinction on the menu.
