embedding youtube video

I've made a short vid of some training I recently did, and want to embed it in my blog so my training friends can see it.  When I paste the youtube 'embed' string in my blog using the html function, I can see the youtube video embedded nice and neatly in my blog (once I click save/OK).

However, if I hit refresh or leave/return to the page, it's been replaced by a shorter string that doesn't show the video.  Somehow it's being stripped out.

Here's the code that I'm sticking into the blog using the html function:

<object width="445" height="364"><embed type="application/x-shockwave-flash" width="445" height="364" src="http://www.youtube.com/v/qnlodP7815I&hl=en_GB&fs=1&color1=0x2b405b&color2=0x6b8ab6&border=1" allowscriptaccess="always" allowfullscreen="true">


And it looks great once you click OK to save it:




But once you exit the page and come back, it's been stripped and converted to:

<object width="445" height="364" data="http://www.youtube.com/v/qnlodP7815I&hl=en_GB&fs=1&color1=0x2b405b&color2=0x6b8ab6&border=1" type="application/x-shockwave-flash">

which looks like this:


So I guess clearly the blog doesn't allow certain types of tags/html code, but having the ability to stick in youtube videos would be really slick, especially ones of events/runs/courses/injuries etc.   Can this capability be created or is it already available via some alternate method?
