Video is choppy but the seepage is apparent.

Yesterday evening on CNN,  Houston oil expert Don Van Nieuwenhuise mentioned a possible fault or crack in the earth that could be leaking. BP was said to be performing additional sonar to learn more.

CNN Expert: BP “double checking” possible “FAULT — a crack in the earth” with new sonar around oil gusher

Don Van Nieuwenhuise interview, CNN’s Situation Room, July 16, 2010 @ 6:45pm EST:

And they’re even getting additional vessels with the side scan sonars to scan even larger areas just to make sure there’s not a leak somewhere else around perhaps if there’s a fault, a crack in the earth, that they know about from their previous seismic that could be leaking.

They’re double checking this.
