Striping out relevant bits of content

Hi,

I hope this is the relevant section to post this query, since the ‘advanced’ section seems to be only for moderators.

I am using the theme GameZine and I am customizing it to my needs. Now I have embedded a video to a post and this post is being displayed in the sidebar. I want only the video to be shown in this sidebar, and not the entire content (which shows up with memes, ads etc.)

So, I want to strip out the unnecessary content and display only what is embedded. How do I do this? Can anyone guide me on this?

This is the content in the theme file that is pulling the post.

$my_query = new WP_Query('category_name= '. $video .'&showposts=1');
while ($my_query->have_posts()) : $my_query->the_post();$do_not_duplicate = $post->ID;

This is the HTML source of the rendered page

<div id="fvideo">

The bold part is the content that I want to keep, and I want to strip everything else out.
