I have an external Sony DvD RW Dual Layer with Nero 7 that I'm very happy with. I don't have too many problems with burning. What I want to know is why when I burn a dvd, does whatever I'm burning, get copied into my hard drive? It gets to be a nightmare trying to find these copies to remove them to free up space. I don't create a log unless there is a problem with burning. Any help is appreciated.
