difference between the two dvd's?

yes i want to buy the dvd of family plot but i'm not sure which to buy.......the one that's been out since 2001 titled "the alfred hitchcock collection" above the title or the newer release that was issued this year with the title "an alfred hitchcock masterpiece" at the top of the dvd above the title.
are there any huge differences between the two? i believe they both come with the same special features.
thanks!
