Ok. I'm running AME 2.5.6, which differs from your 2.5.

Here is my youtube definitions for quick comparison if you like:

Regular Expression:

http://[\w]+\.youtube\.[\w]+/watch\?v=([\w-]+)[\w&;=-]*[\#t=]*([\d]*)[&;10shdq=]*

Replacement:

<object width="$ameinfo[width]" height="$ameinfo[height]">
<param name="movie" value="http://www.youtube.com/v/$p1&fs=1&start=$p2"></param>
<param name="allowFullScreen" value="true"></param>
<embed src="http://www.youtube.com/v/$p1&fs=1&start=$p2" type="application/x-shockwave-flash" allowfullscreen="true" width="$ameinfo[width]" height="$ameinfo[height]" wmode="transparent"></embed></object>

Validation:

value=&quot;http://www\.youtube\.com/v/([\w\-]*)?&amp;

Hope that helps! Now if someone would kindly comment on my Local Hosted Media question from Post #1511!
