For example:
Single trailer:

Apple quicktime container. Can contain many different formats, starting from very simple old sorensen codec to HDTV content in h.264 (MPEG4/AVC). For trailers, its often ok to download and play these files. In this case, the file is a redirect to http://images.apple.com/movies/wb/happy_feet/happy_feet-tlr2a_h320.mov , so people have difficulties to locate the real file.
Your best chance are full featured big media players like mplayer, though only quicktime is guaranteed to work.
