Quicktime doesn't support playlists to my knowledge. You could add the files to a playlist in iTunes, or download VLC. I'd highly recommend VLC, it's free, it can tackle pretty much any format you can throw at it (including .mov), and you can just drag and drop files to a playlist to queue them up very simply.

Quicktime Player (X or version 7) doesn't support playlists to my knowledge. You could add the files to a playlist in iTunes, or download VLC.
