I have been running Sony equipment here along with plextors at times. But I usually see the best with the Sonys for both dvd and vcd projects. As far as trying to multiple burn dvds at the same time with one program that's out of the question there. When burning a disk the drive letter for the available burner is chosen where that one single drive then writes the disk accordingly. With two drives you could go back and forth for each new project. You can also set the number of copies to burn when creating a new project to burn on one drive by assigning that drive's letter. That may require saving the new project first.
