Challenge accepted. Will try to find a DVD with some of that stuff tomorrow (it's 3:18am, parents would not appreciate).
Edit: Does searching a dvd count as time spent before being able to watch the movie? Since you can't, ahem, copy dvds to your NAS (they're encrypted with CSS to prevent yarr pirates y'know).
Unskippable previews, menus, etc. can be more common in rental-only versions of DVDs and BDs. Try a Redbox or other major rental store (if any exist) if you want to increase your chances of finding such a disc.
