I wonder if this is the correct place to be posting this, so someone correct me is so, but I was wondering what the best place to find THX demos/trailers. Is there a DVD available with a lot of them, or are they available only at the start of certain THX certified movies. I noticed that the Toy Story and Indiana Jones DVD's as well as Finding Nemo DVD have different THX trailers, but not sure where to find any others. I have heard about a "cavalcade" trailer but have never seen it. Help! Maybe an ebay purchase? I get a little weary of that, though.
