I guess my site was hit by Panda too.. I said guess because all of us are guessing since Google does not bother to inform us. Like you, searching for a keyword, previously lands you in the first page - now it's on the 4th/5th page. Try searching your site on Bing, Yahoo and see.. videowatchr.com uses Google video search and the youtube API to show youtube videos. So of course, it will have duplicate content. If you use an API, you are getting someone's content most likely, does that make you a content farm? How about if you use an RSS feed? Google should publish guidelines on this Panda - so we're not guessing.
