HI Ketlad,
I'm not 100% sure on your model, but it seems pretty much like a Huffington Post, which is take others content and regurgitate it? If so Egol has a point to a degree which is, you're dealing with big names and little control over what content is generated. If Hulu or Youtube post a video sure you may have a page for it, but if somebody is already at their site why would they go to yours to watch it?
I understand there are a crap ton of video sites, most of which I personally would never visit unless they had something nobody else had and I was pointed to the site by another person. That said, it should provide some insight as to what you can do. Try to understand why people go to these types of sites and what you can do to fill those desires. Additionally getting the word out about your site can be done by visiting forums and blogs and posting (not spamming) links to videos that may interest the community you are engaging with. Granted 3k to post links on a forums and blogs per month sounds like a lot but if your assistant uses the correct approach it could certainly bring traffic.
If you have the resources, skills and knowledge to understand why people use X site, and you can fulfill those desires and even make it better then you could do really well. You may have to take things to the next level, maybe a virtual museum that a person can design, and take people on tours of their favorite videos.. I know few sites are doing this with Pictures now, surely videos would be better. Anything you can do to put some power in the users hands give them control over what they see how they see it, and what they can do with it, would be a plus.
That is just my thoughts I hope it helps.
