TechCrunch 50, what the Huffington Post is calling the ‘Sundance of Startups’, is taking place in San Francisco.  The event showcases 50 startups, fighting for attention from VCs, journalists, and business partners at the event.  TechCrunch is live-streaming the entire event via uStream along with behind-the-scenes interviews with presenters like Penn (from Penn & Teller) and Google’s Marissa Mayer.

For those who’d rather surf through the event’s footage with a remote,  Boxee App guru Rob Spectre has put together a clean application to give you access to the conference’s online video content.  Watch the action happening right now using the “watch live” feature or choose from behind the scenes videos with Mike Arrington and some of the presenters / attendees at the show.

Here’s a peek at what it looks like.

Best of luck to all the startups presenting there, and thanks to Rob for another good app.
