VHS: The Wizard of Oz
DVD: About a dozen all at once, that included the Wizard again, plus the first Indiana Jones, first Star Wars, a couple of 1930s Errol Flynn movies, Monty Python and the Holy Grail, Woody Allen's Radio Days, Victor/Victoria, and the first Godfather movie.
BluRay: nothing yet, gonna wait to buy a player when I choose an HDTV that can use it. Gave my last HD away to my ex-BF when I moved, while the TVs have continued to evolve & prices drop. So not sure when to take the plunge again, and hubby is in no hurry, either.
