I have installed a LG GSA 4160B DVD/CD multi disc drive unit. With the drive unit came Nero Express, which I understand is a reduced version of Nero 6. I also have Roxio 6 CD/DVD Creator. I wish to use DVD-RW discs for multisession burning but find both programs completely fill the disc regardless of the size of the data recorded. How do I set one or both programs for multisession burning or is that not possible? It was previously with Roxio 6 on another drive unit and CD-R/RW discs. The OS is Windows XP Home. Thank you all in anticipation of your help.
