I'm looking at different options for a laptop, and noticed I have a choice between:Combo Dual Layer SuperMulti 8X DVDRW Drive w/ Software4X Blu-Ray Reader / 8X DVDRW/CDRW Super Multi Combo Drive 4X Blu-Ray Writer/Reader + 8X DVDRW/CDRW Super Multi Combo DriveI can't quite tell what each one offers exactly. What I want is the ability to play Blue-Ray as well as regular CDs and DVDs, but also the ability to burn CDs. The 3rd option sounds like it means it can burn Blu-Ray discs, but I do not want that option, I just want to be able to burn CDs and such, but I can't tell if the 3rd option implies that it is the only one with a burner?
