Preg_match_all: Why does "this" match, but "that" won't?

Question

So, I'm basically trying to match something inside (and including) object tags using this:

<?php preg_match_all('/<object(.*)<\/object>/', $blah, $blahBlah); ?>

He finds a match for this:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="400" height="250" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="src" value="http://vimeo.com/moogaloop.swf?clip_id=9048799&amp;server=vimeo.com&amp;show_title=1&amp;show_byline=1&amp;show_portrait=0&amp;color=&amp;fullscreen=1" /><embed type="application/x-shockwave-flash" width="400" height="250" src="http://vimeo.com/moogaloop.swf?clip_id=9048799&amp;server=vimeo.com&amp;show_title=1&amp;show_byline=1&amp;show_portrait=0&amp;color=&amp;fullscreen=1" allowscriptaccess="always" allowfullscreen="true"></embed></object>

But this will not match this:

<object width="400" height="300"><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=5630744&amp;server=vimeo.com&amp;show_title=1&amp;show_byline=1&amp;show_portrait=0&amp;color=00ADEF&amp;fullscreen=1" /><embed src="http://vimeo.com/moogaloop.swf?clip_id=5630744&amp;server=vimeo.com&amp;show_title=1&amp;show_byline=1&amp;show_portrait=0&amp;color=00ADEF&amp;fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="400" height="300"></embed></object>

Any idea why? Thank you for understanding.

ETA: Since my approach may have been erroneous to begin with, here is some information on what I'm trying to do.

This is for the Wordpress site. I am using a plugin that converts shorttag to full video embed code. The plugin was recently (fortunately) updated to make the code more valid.

The function I'm trying to create is simply to find the first video object in the message and capture it for use elsewhere on the site.

( , Wordpress):

<?php
function catch_that_video() {
  global $post, $posts;
  $the_video = '';
  ob_start();
  ob_end_clean();
  $output = preg_match_all('/<object(.*)<\/object>/', $post->post_content, $vid_matches);
  $the_video = $vid_matches [1] [0];
  if(empty($the_video)){ $the_video = 0; }
  return $the_video;
}
?>
