 var vidWidth = 425;
 var vidHeight = 344;

 var obj = '<object width="' + vidWidth + '" height="' + vidHeight + '">' +
     '<param name="movie" value="http://www.youtube.com/v/[vid]&hl=en&fs=1">' +
     '</param><param name="allowFullScreen" value="true"></param><param ' +

     'allowfullscreen="true" width="' + vidWidth + '" ' + 'height="' +
     vidHeight + '"></embed></object> ';

 $('.content:contains("youtube.com/watch")').each(function(){
  var that = $(this);
  var vid = that.html().match(/(?:v=)([\w\-]+)/g); // end up with v=oHg5SJYRHA0
  if (vid.length) {
   $.each(vid, function(){
    that.append( obj.replace(/\[vid\]/g, this.replace('v=','')) );
