Video lectures from the world's top scholars

Academic Earth claims to have Video lectures from the “world’s top scholars”. While, in many ways, I agree, they’ve only (at present) got those from US universities – so have eliminated all non English speakers, as well as those English speakers from, well, anywhere that’s not the US!
The computer science strand has 13 sets that are lecture series, so could be useful.
