In my experience, solid OB is the basis for any good duck dog. Solid OB just happens to produce a well behaved family dog as well. Retriever training will result in a good family dog by default simply from solid OB.
For videos, I'll throw Chris Akin's Duck Dog Basics I & II into the hat. His methods are simple, they work, and he explains them very well. My dogs responded well to the training methods he taught in the videos.
I've heard good things about Hillmann's & Lardy's stuff as well.
I personally did not like Dokken... his book or DVD.
