How can a Blu-Ray drive (with a Blue Laser), read a regular DVD, which requires a Red Laser? Do Blu-Ray burners also have a Red Laser? Also, since Blu-burners DO read regular DVD's, are they as accurate as a Red Laser?

I've asked this question many times, but nobody seems to know the answer.

Yes, the drives use multiple lasers.

"There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.'" -- Isaac Asimov
