I was simply searching for a temporary solution to the problem. What would be ideal is that ImgBurn could write to multiple drives at once using only on instance of itself. I'm part of a rather small company that frequently needs to make as many as 60 copies of a cd, but not frequently enough to warrant buying a cd duplicator (hundreds of $). Instead, we have multiple cd drives. I was using Roxio 7 to accomplish this task, but can't since moving to Vista 64bit as it isn't support. If ImgBurn could write to multiple drives simultaneously, it would the first one that I have found that is compatible with Vista 64bit. Not even Roxio's latest product supports it (try to figure that one out).
