ERROR WITH EMBED YOUTUBE VIDEO

I added a video to youtube, this one:

<object width="425" height="350"><param name="movie" value="https://www.youtube.com/v/1GKaVzNDbuI"></param><param name="wmode" value="transparent"></param><embed src="https://www.youtube.com/v/1GKaVzNDbuI" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"></embed></object>

and when I go back to edit it,, it turns the code automatically to this:

<object width="425" height="350">
<param name="movie" value="https://www.youtube.com/v/1GKaVzNDbuI"></param>
<param name="wmode" value="transparent"></param></object></p>

When I try to fix it, it wont do it…
