Embedding a video issue

Hi,

Could someone help me show how to adjust the size of the youtube video that I’m trying to embedded in my blog post. I want to have the exact same size like the one in the merchant page of the product I’m selling:
(http://winhimback.com/affiliates/pre-sell-video)

On that very page, the merchant said to paste the following code:

<span class=”mceItemObject” width=”640″ height=”385″>
<span name=”movie” value=”http://www.youtube.com/v/t6v4ra9EjWA?fs=1&hl=en_US” class=”mceItemParam”></span></param> <span name=”allowFullScreen” value=”true” class=”mceItemParam”></span></param> <span name=”allowscriptaccess” value=”always” class=”mceItemParam”></span></param><span class=”mceItemEmbed” src=”http://www.youtube.com/v/t6v4ra9EjWA?fs=1&hl=en_US” mce_src=”http://www.youtube.com/v/t6v4ra9EjWA?fs=1&hl=en_US” type=”application/x-shockwave-flash” allowscriptaccess=”always” allowfullscreen=”true” width=”640″ height=”385″></span></span>

So, I went ahead and paste that in my html on the blog post… but it’s not working at all. What I tried is I went into the youtube and get the embedded code (http://www.youtube.com/watch?v=t6v4ra9EjWA&hd=1) but the video size that show is about HALF smaller than the one on the merchant page. Could someone show me how to fix this thanks.
