Which title is the one I should backup? My LOTR EE comes in two DVD's, DVD1 has half of the movie and it has two titles; Title1 is 3,579MB and Title2 is 3,585MB. I am using DVDShrink 3.0 beta. So basically what is the difference between the titles? DVDShrink preview shows that both titles are the same, but could there be something different in the audio or something? Thanks.
