I had this same problem when I first tried to play Halo 2 online. Because of the system Bungie/Microsoft uses to create the playlists, you Have to have ALL the maps that have come out in order to play, and it can take a while to download em all, depending on connection speed etc. I'd say 2 hours for all 4 packs.
