No, because I don't want to work on the version 2 anymore and version 3 need to restart from the scratch so... when I will have a new version that really works (just for video first... not playlist, audio, etc) I will create a svn repository (I need to learn how it works ) then anyone could contribute.

Actually, I have done 2 pieces of the puzzle : a script that check if jquery is loaded before starting the dom conversion ; and the interface XML/XSL with jquery effects and CSS optimisation to make it easier to customize : demo (yet a draft)
Here the test.php code (it will be the future "link" page (jquery is not enable in this page actually) and the "player" div is call by ajax in the test.html file.) :

<?php
function translate($text) {
    return $text;
}
// Load the XML source
$xml = new DOMDocument;
$xml->load('cache/test.xml');</p>

<p>$xsl = new DOMDocument;
$xsl->load('skins/default/video.xsl');</p>

<p>// Configure the transformer
$proc = new XSLTProcessor;
$proc->importStyleSheet($xsl); // attach the xsl rules</p>

<p>$result = $proc->transformToXML($xml);</p>

<p>$result=str_replace("<lg>","<?php echo translate('",$result);
$result=str_replace("</lg>","') ?>",$result);
$result=eval("?".chr(62).$result.chr(60)."?");</p>

<p>echo $result;
?>

So if you want to submit improvement for the version 2 you will be the only master on board. ( josephk at itheora.org to send me explanations and files)
