Hack turns NEC's DVD burner into a double-layer burner

This is helpful for about three people, but hackers have created a very unofficial upgrade for NEC's 2100A and 2500A DVD burners that lets them burn to those new double-layer recordable DVDs that can hold twice as much data on them than regular DVD-Rs. Saves you the expense of having to buy a whole new DVD burner (something we're sure NEC will be thrilled about), but we wouldn't recommend this for anyone who isn't prepared to destroy their drive in the process.
