add the following code at the bottom of bb_config.xml:

	<match name="youtube">
		<regex>(?i)\[youtube\]http\:\/\/www.youtube.com\/watch\?v\=(.*?)\[/youtube\]</regex>
		<replace>
		<![CDATA[
		<object width="425" height="350">
		    <param name="movie" value="http://www.youtube.com/v/$1"></param>
		    <param name="wmode" value="transparent"></param>
		    <embed src="http://www.youtube.com/v/$1" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"></embed>
		</object>
		]]&gt
		</replace>
	</match>

go to Admin Panel -&gt Cache -&gt Reload BB Code and it's done.

Usage:

[youtube]full URL of the YouTube Video[/youtube]

See http://www.andowson.com/posts/list/109.page for live demo.

The original post only supports URL in the form "www.youtube.com". However, if you change to another form, like "youtube.com" or "tw.youtube.com", it will not work. So, we need to modify the original bb_config.xml as follows:

        <!-- YouTube -->
        <match name="youtube">
                <regex>
                        (?i)\[youtube\]http\:\/\/(.*?)youtube.com\/watch\?v\=(.*?)\[/youtube\]
                </regex>
                <replace>
                        <![CDATA[
      <object width="450" height="370">
          <param name="movie" value="http://$1youtube.com/v/$2"></param>
          <param name="wmode" value="transparent"></param>
          <embed src="http://$1youtube.com/v/$2" type="application/x-shockwave-flash" wmode="transparent" width="450" height="370"></embed>
      </object>
      ]]>
                </replace>
        </match>

Now, the new form of URL works.
