That being said, I've grappled with hundreds of novices who have also watched grappling. If it helped them, it was pretty insignificant. Even if one has seen it, without understanding the basic principles, the skillset is too complex to keep him from making basic mistakes and getting finished (i.e. don't push up when mounted, don't leave on arm in and one arm out in the guard, don't drop the head when doing takedowns, etc).
POR is crucial here (point of reference).
Someone with a judo back ground can pick up a lot of BJJ ( as an example) from videos, just as a shotokan guy can pick up TKD.
Of course this depends of the person, many people WATCH instructionals and have no idea HOW to use them.
Of course some instructionals just suck while others are very good and focus not so much on "teaching" but on making clear key points of what NOT to do and what to do.

Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
