when i copy a retail version of a game then try to copy the backup alcohol says there is not enough room on this disk even though i'm using the same type of disk (infiniti)
Try DVD Decrypter instead, it works great for backing up games and is free. you should have no problem backing up a back up. Also be sure the message is telling you that there is not enough space on the disc, and not that there is not enough space on you hard drive to store the temporary files.
