Need a Responsive Video Plugin

Hello,

Can someone recommend a plugin (premium or otherwise) that will help me embed responsive videos?

I want to embed the following:
YouTube videos
TED Videos
Vimeo videos
Slideshare presentations

My blog url is workreadplay.com and I am using the WordPress 3.5.1 with a premium theme from YooTheme. I use WP-Markdown to write posts so ideally the plugin will work with this.

Thanks for the help.
