Not sure if this will make sense or not but I have 2 dvd burners in my machine and was just wondering if it is possible to enable nero to burn 2 disks at once rather than burn 1, eject it and put another disk in the same drive.
Yes, you can burn to more than 1 disc at the same time but it has to be from the same source. For example you could burn 2 copies of the same disc at the same time but not discs 1 and 2 of a set. When you select to Burn there's a tickbox to use multiple recorders. Tick that and it'll then ask you to select the drives to burn to.
