Hi spiesfan Nero will can burn to multiple burners at once with the full version - oem versions don't support this. Or you can set the # of copies you want if just using 1 drive with several of the different apps in Nero.
You can batch encode using DVDRebuilder, Meaning it will encode several files one right after the other, but you still have to burn the files seperately. I don't know of a program either that will batch burn.
