Hi,
You can embed the video in your site by copying the code where it says embed on youtube e.g.
<object width="425" height="349"><param name="movie" value="
http://www.youtube.com/v/_jMpwyuZSwc&hl=en&fs=1&color1=0x2b405b&color2=0x6b 8ab6&border=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/_jMpwyuZSwc&hl=en&fs=1&color1=0x2b405b&color2=0x6b 8ab6&border=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="349"></embed></object>
Or you can just use the link (bit in red above)
