Gives you a shortcode for Youtube-Videos and makes a preview-pic for this Video and realizes to watch the video with fancybox for wordpress oder prettyPhoto or in a extra tab. You choose, what you want.
The URL ist for example: http://www.youtube.com/watch?v=XmRLJ4XvpZk 
The shortcode is
<pre><code>[ytcode ytid="XmRLJ4XvpZk"]
[ytcode ytid="XmRLJ4XvpZk" tit="Vemma Strategie Deutsch"]
[ytcode ytid="XmRLJ4XvpZk" tit="Vemma Strategie Deutsch" x="800" y="488"]
[ytcode ytid="XmRLJ4XvpZk" x="800" y="488" ppic="2"]
[ytcode ytid="XmRLJ4XvpZk" ppic="default"]
[ytcode ytid="XmRLJ4XvpZk" fso="v"]
</code></pre>
<ul>
<li>Options:</li>
<li>
float=”left|none|right” 
if float is none, you can choose the alignment:
</li>
<li>
align=”left|center|right”
</li>
<li>
fso=”h|v|n” 
horizontal, vertical, none filmstripes
</li>
<li>
ppic=”default|1|2|3″ 
takes the previewpic from youtube. This are the four possible picture-names.
</li>
<li>
vb=”prettyphoto|fancybox|blank” 
if installed it uses prettyphoto or fancybox. Or it opens the video in a new tab (target=”_blank”)
</li>
<li>
pfeil=”FF0000″ 
the color of the arrow is now red
</li>
</ul>
<h3>Arbitrary section</h3>
*Known Issues: 
 – Publishing an Artikel/Site or update ist can cause an error-message “Warning: Cannot modify header information – headers already sent by (…)” 
 maybe this is theme specific or it depends to other plugins!
<h3>A brief Markdown Example</h3>
Unordered list:
<ul>
<li>Make opacity from the overlay-pic with the arrow on the preview-pic adjustable</li>
<li>resizing of the previewpic doesn’t work correct!</li>
</ul>

Titles are optional, naturally.
Markdown uses email style notation for blockquotes and I’ve been told:
<blockquote>
Asterisks for emphasis. Double it up for strong.

<pre><code><?php code(); // goes in backticks ?>
