i need some advice on a theme for creating a web-based broadcast network

okay. so, i'm wanting to create a multimedia broadcasting company on my multisite.

videos, classes, membership; etc.

what theme would you all recommend?

also, I wish to have a buddypress aspect to the multisite, that is very visually customizable so that I can GRAPHICALLY design something that is constant across the entire multisite.

recommendations?

(yes, asking for recommendation on two themes to suit my purposes)
