cannot write compilation to selected recorders simultaneously

I am trying to burn a Nero .nrg image file to an Aleratec 4 stack DVD burner but keep getting this error message. The original disk is DVD-R and I have tried Maxwell DVD-R, Verbatum DVD+RW, and now TDK DVD-R.

The image burns to the DVD burner in my laptop. It also burns to the Stack burner ONLY if I select one drive, not 2 drives.

Windows Vista. Nero version 8.

Any suggestions?

 

This is CRAZY!!! I opened Nero up 4 times, so the program is open 4 times at once. Open Nero program #1 is burning the image to my main DVD drive (drive D). Open Nero program #2 is burning the image to the 1st Aleratec Drive, E. Open Nero program #3 is burning the image to the 1st Aleratec Drive, F. Open Nero program #4 is burning the image to the 1st Aleratec Drive, G.

So I can get the computer to burn the image simultaneously to 4 burners, but only if it thinks that each open Nero program is NOT burning simultaneously

 

Movie? Game? Data? What are you working with? File size? Reason you need to burn four at once?

 

This was a DVD video of a football game. i used the Copy mode of Nero Burning Rom to make the .nrg ISO file.

I am a football coach and i have to burn 30-40 copies of every game for coaches & players.

 

At this point I think I would go here first:
