I wanted to get a thread going on people's views of who they think puts out the best DVD's ( they can be instructionals or not) on WC and WHY they believe those DVD's to be top notch.

This is not about learning from a DVD, though some are better than others for that, nor is it about whether one CAN learn from a DVD, that is another topic.
Its about which DVD's seem to, in your opinion, show WC how it is "supposed" to be done.
