One of the good things about the MIT videos is that they don't have the amount of "administrative stuff" which the Berkeley lectures have (ie stuff about where this and that lecture will be next week etc etc). So the berkeley lectures could do with editing that out. OTOH I think Brian Harvey is a very good lecturer as are abelson and sussman. Sound quality on one or two of the MIT lectures is poor in parts. If you have time might not be the worst idea to watch both sets. Edition 1 of the book was current for the MIT videos whilst edition 2 is current for the berkeley series.
