OP, do you have any manual actions in GWT? Either way, work on adding unique content and make sure you noindex thin pages like these: Frequently asked questions

From reading around here it seems like some tube sites are starting to run into the same issues that cam white labels have encountered, in that if your tube contains the same videos with the same descriptions as a ton of other sites google can smack you in the SERPs for lack of unique content. That's Panda (the content algo), but you may be affected by Penguin (the link algo) as well. Do you recall when this first happened? That could go along way to pinpointing the source of the issue as you could then compare the date to google algo updates

but yeah, something's up and probably won't change until you identify and fix the source (either the content, your link profile or both)

that would be my advice anyways, good luck however you decide to proceed
