START = FILEOPEN

FILEOPEN, which is the default value, makes the movie start when the file is opened.

For example, this code

<IMG
SRC="/graphics/moonflag.gif"
DYNSRC="/graphics/moonflag.mpg"
START=FILEOPEN
ALT="Astronauts on the moon">

starts the movie as soon as the page is opened:

START=MOUSEOVER >>>
