The Great Escapes and Counters DVD by Gustavo Machado
Product Review (submitted on July 18, 2009):
high quality video instruction and excellent techniques. Escapes are so important because there's nothing worse than getting caught in a triangle and your one escape technique is countered. Saulo Ribeiro's book on BJJ posit that a blue belt should focus on survival first. You have to be able to fend off attacks. Nothing is worse than fighting a bigger, stronger, more athletic opponent and your attacking game is nullified. It's very solid.
