Lightbox video issue

[daniel.martin.alonso]

Hello,

I have a production site with the "pretty young" theme, and I'm using Shadowbox JS plugin to show the images and videos with a lightbox effect. It worked fine for me in different sites, but in this particular site it's doing something strange.

The issue is found in Firefox 5.0.1 and Internet Explorer 8. It's working fine in Safari and Chrome. The problem is that when I click in the video, it should open in a lightbox window but, instead, it's being opened in full window. Any ideas?

A couple of URLs:

- http://www.papaenapuros.com/testing/: this is the production site where I have the issues.
- http://demos.despachotres.com/testing/video/: this is a testing site with the same code.

I've tried to disable all the plugins, but didn't work. The funniest thing is that if I take the source code from the browser and save it in a local file, it works fine in all browsers.

Any idea??? Thanks in advance.
