NOTE: Although most of these trailers and video clips are flash or mp4, so make sure that your player is set for those types.
I recommend that you set your viewing size option to "original", although some are quite small and you might want to double the size of those; full screen is not recommended for most of the mp4s.
Android users may need to check out the following to get mp4 clips to play -
