I have seen many DVDs where Title Set 1 was *not* the main feature; I
don't think Title Set 1 = main feature is a safe assumption. If the
DVD is a movie, you can look for the largest Title Set. But
generally, you have to look at each Title Set to see what they are and
determine which Title Set corresponds to which "title" on the DVD.
