Multisession Easy Solution
I have a Plextor 708uf and a plextor 20/10/40 (I think the number is 320) anyway the program came with Oak Software. The oak software allows me to record a Multisession disk with no problem in about half the time as the Microstudio software. This only works on Multisession disks only. All other disks you need the Microstudio software. The Oak software reconizes the disk as a Data Disk.
Try it, it works well
