Hehehe, I like this...
Well, I tend to have an archive of all my backups self bootable and in .NRG format so if I want to re burn them, I just double click on the file itself (.NRG) which already opens Nero in the Burn screen, then you just click on the BURN button. 3 clicks in total (2, if you have doubleclick assigned to the middle button of your mouse

)
Now, with DJ, you open DJ (1), click on CDI->CD icon (2), choose image (3) then BURN (4).
Which one did u say is faster?
