Agree - less images. The first page seemed overwhelming and there was no simple sense of how to navigate where I wanted to ... One thing that would help, is something I think youtube should add - which is while you are watching the video, click on another thumb of another video and be able to "add to que" so as soon as the first video is over it rolls to your que
Change your site to a BLACK AND WHITE site. This means that you should not have too much images, you should not have too much dark or light colors .. make it balanced and you are on your way !
Black & White would be ideal .... maybe the ads shaded gray ... More like a newspaper is what I would aim for Seems you have some decent traffic though, congrats !
