The first thing you need to you is look through the index on the site for each one and see what is available for each film.
If you go to Civil Registration and view the "title", you get: Estratti dei nati, notificazioni, e morti per varie regioni nel nord-ovest di Italia ( FHL INTL Film
1075768 Item 3 is the film available for this)
English Translation: Miscellaneous extracts of births, marriage publications, and deaths for various regions of northwestern Italy
If you click on that you will get a screen with more info and an icon to view the film notes.

Now I'm not sure of the correct procedure in Italy, but here, I would go to my Family History Center and order the film. It would cost me $7.00 to view the film for one month. In the US it only costs $5.50. I would wait for the film to arrive (anywhere from 3 weeks onwards). The FHC calls when it arrives and I book an appointment to view the films on one of their readers. At thats pretty much it.
Maybe Riccardo can advise if the procedure is the same in Italy?
