Ray Kurzweil is the host. Questions begin 18 minutes in.
Memes only get a brief mention at the very end of the video. They don't get very much space in the book either.
Dawkins gives his take on the evolution of cooperation near to the end in response to a question. Kin selection and reciprocity get mentioned. Group selection does not.
Another recent video has Dawkins being interviewed by Michael Shermer. Again the evolution of cooperation is a significant theme.
