The extraction of the video title fails because there is something wrong with the regex.
This happens when the video title has characters such as .?!

I noticed this seems to happen only when you are logged in.
The dump-page contains redirect to the front page of Crunchyroll and doesn't seem to contain the video page.

So if you are ok with this, I shall not post it, because I don't feel like looking for any preferences to my personal account. It doesn't seem to have anything of value since there's just a redirect to the front page:

<html lang="en">
  <head>
    <title>Redirecting...</title>
    <meta http-equiv="refresh" content="0;url=http://www.crunchyroll.com/" />
  </head>
  <body>
    <script type="text/javascript">
      document.location.href="http:\/\/www.crunchyroll.com\/";
    </script>
  </body>
</html>

... and the front page.

I should add I'm logged in using netrc.

Can you watch it in browser when logged in?

Yes it works fine on a browser.

There's also the fact that it happens when using rtmpdump, since when logged in as a premium member you need it for HD. When you aren't logged in, rtmpdump isn't used.

Hello Pablo :)
Can You Help me with this problem!

// define meta tags
$meta_title = $video['video_title']; HERE I WANT EXTRA TITLE
$video['excerpt'] = (empty($video['excerpt'])) ? $video['video_title'] : $video['excerpt'];
$meta_description = generate_excerpt(str_replace('"', '"', $video['excerpt']), 150) .'...';

$meta_keywords = '';
if(is_array($tags_arr))
foreach($tags_arr as $id => $v)
{
$meta_keywords .= $v['tag'] . ', ';
}
$meta_keywords = substr($meta_keywords, 0, -2);
// end

I've started to get this same error today, except it's affecting every video on the site regardless whether I'm logged in or not. The error at common.py is slightly different, though. Example of video with no punctuation in title:
