Hi, I just purchased this machine brand new, it can read and write cds as well as dvds, and it can burn cds, but it can not burn DVDs - have tried DVD+rw, and a DVD+RDL (dual layer), multiple times, and they just won't burn. Tried using Windows 8 software, and Ashampoo, and Nero, and still just won't write to the DVD. Device manager says the driver is up to date. Could it be a hard ware problem if it reads DVDs and reads and writes CDs (I mean, could it be a problem with one of the lasers, don't know much about that...) Anyone else had any problem like this? The laptop is brand-new.
