    I noticed that a DVD Player I recently bought said it featured "Dual Laser Pickup". From all my searches on the internet, all I have found is that this "enhances viewing of all formats". Whoopie. Anybody have any good information on what it really does and how it helps? Thanks!

    DVD lasers can't really read CDs well. Dual Laser pickup just means 1 CD laser, 1 DVD

    You'll need a dual lasers or a dual-focus laser if you want to read CD-Rs/CD-RWs reliably (or even at all). CD lasers and DVD lasers are focused at different frequencies, and the comparatively low reflectivity of a burned CD makes it difficult to read with a DVD laser. Regular CDs have a higher reflectivity and are more easily read, even by "wrong" lasers.
