[Plugin: MarcTV Video Embed] Resizing vimeo video

Hello, I think this plug in is great. What I need to do is be able to change the size, when I add the URL the result is 100% width of the page. I tried adding a <div> around the video to adjust the size, but that did not work.

I would also like the video to be responsive to size of the browser. Thank you 🙂
