I believe this will operate as you intend:
Code:
<object width="425" height="344"><param name="movie"
value="http://www.youtube.com/v/fxspk5ioT9c&hl=en&fs=1&autoplay=1"></param><param
name="allowFullScreen" value="true"></param><param name="allowscriptaccess"
value="always"></param><embed src="http://www.youtube.com/v/fxspk5ioT9c&
hl=en&fs=1&autoplay=1" type="application/x-shockwave-flash" allowscriptaccess="always"
allowfullscreen="true" width="425" height="344"></embed></object>
