I've backuped my development tree to a DVD media (about 4.3GB), and have to make a copy of it.
There are a lot of files and I would like to perform a direct copy from 1 DVD media to another one, the same way as it's performed using the CloneCD (copy on-fly).
I've tried to use Nero, but it copies all the files to a temporary folder and only then writes them on the target DVD. It takes plenty of time.
The main issue is: how to make it work on-fly (without the temporary storage), like the CloneCD does.
