No Output on page

The plugin simply does what it does I am afraid. If theme is not displaying it, it is possible that the tabs have been already filtered in the theme you are using.

Would it be possible to have a copy of the theme to test on. If so, please send it to me via my contact form on my site http://www.sebs-studio.com/contact/

I am acutally making improvments as to how the video tab is shown on the product page making it more theme friendly.

I will take a look at the problem with the current release of my plugin and also test it with the new version I am currently coding.
