If you need to embed a high quality video on your blog, there is an easy hack for that. Just append ap=%2526fmt%3D18 onto the end of the YouTube URL, like so:

<object width=”425″ height=”344″><param name=”movie” value=”http://www.youtube.com/v/IQx464qXwZo&hl=de&fs=1&ap=%2526fmt%3D18“></param><param name=”allowFullScreen” value=”true”></param><param name=”allowscriptaccess” value=”always”></param><embed src=”http://www.youtube.com/v/IQx464qXwZo&hl=de&fs=1&ap=%2526fmt%3D18” type=”application/x-shockwave-flash” allowscriptaccess=”always” allowfullscreen=”true” width=”425″ height=”344″></embed></object>
