Bin ja auch nicht der große Fachmann, nur ich hätte wenigstens mir mal die Dateien angesehen, und versucht das zu ändern.
z.B. hier ändern, oder https hinzufügen
"youtube" => array("#^http://([^.]+\.)?youtube\.com/(watch_private|watch)\\\\?.*[?&]v=([^&]+)#",
3,
"http://www.youtube.com/v/{ID}",
null,
MS_BBCODE_YES,
"http://www.youtube.com",
"http://img.youtube.com/vi/{ID}/default.jpg", //works<!-- http://code.google.com/apis/youtube/player_parameters.html -->
<object
width="{if image_width}{image_width}{endif image_width}{ifno image_width}480{endifno image_width}"
height="{if image_height}{image_height}{endif image_height}{ifno image_height}295{endifno image_height}"
>
<param name="movie" value="http://www.youtube.com/v/{media_id}&fs=1&autoplay={image_autoplay}" />
<param name="allowFullScreen" value="true" />
<param name="allowscriptaccess" value="never"></param>
<embed
width="{if image_width}{image_width}{endif image_width}{ifno image_width}480{endifno image_width}"
height="{if image_height}{image_height}{endif image_height}{ifno image_height}295{endifno image_height}"
src="http://www.youtube.com/v/{media_id}&fs=1&autoplay={image_autoplay}"
type="application/x-shockwave-flash"
allowscriptaccess="never"
allowfullscreen="true"
></embed>
</object>
Ob das was bringt hätte ich dann bestimmt erfahren
