One would imagine that if this is a commercial instructional DVD, you have to BUY the code to watch it.
BTW, with video piracy approaching the glory days of Napster with BitTorrent and the like, can you blame any manufacturer for NOT making instructional DVD's? They cost a LOT of money to do well, and show little chance of making a profit (or even breaking even!)...
Let's face it, if this clip didn't need a code, how many of us would have downloaded it for free?
