Embedding YouTube Videos

How do I fix the fact WordPress keeps doing something to my <object> tags.

Turns this:
<object height=”355″ width=”425″>
<param name=”movie” value=”http://www.youtube.com/v/1FJHYqE0RDg&rel=1″></param&gt;
<param name=”wmode” value=”transparent”></param><embed src=”http://www.youtube.com/v/1FJHYqE0RDg&rel=1&#8243; type=”application/x-shockwave-flash” wmode=”transparent” height=”355″ width=”425″></embed>
</object>

Into this:
<object height=”355″ width=”425″></object>

<param name=”movie” value=”http://www.youtube.com/v/1FJHYqE0RDg&rel=1″></param&gt;
<param name=”wmode” value=”transparent”></param><embed src=”http://www.youtube.com/v/1FJHYqE0RDg&rel=1&#8243; type=”application/x-shockwave-flash” wmode=”transparent” height=”355″ width=”425″></embed>

Thanks,
