dvd shrink 3.2 - cannot preview titles :(

[ken.vs.ryu]

dvd9 backed up using dvd decrypter.
want to back up using dvd shrink 3.2.
i see the menus - ok.
i see main movie - title 1,2 and title 3,4 - both 3.5gb each

i would like to see the difference between 1,2 and 3,4. so i can tell which one i don't need and not back up. so that the part i want is not compressed.

but the play button is not active. any clues?

Use reauthor, whatever is highlighted in blue should play.
