The internet didn't work, so they might have lost the videos anyway. Also the jury didn't really care (Robert Scoble did play solitaire while evaluating the contestants). Two of the 3 finalists were companies that exisited 2 to 5 years. The criteria of choosing them were that they were profitable. They were more like a success story than a startup! Leweb didn't even release a one liner describing each startup. I wouldn't be too surprised if the startup videos will never be released.
