1.	Solve : Can a Dual Layer DVD drive write a Single layer DVD r/CD r?
Answer» Really confused, i accidently deleted my software to burn cds/dvds on my dell laptop, Dell inspiron 1300, it was the SONIC software??? CONFUSED* anyway i want to buy a dual layer DVD WRITER so i can burn my films onto 8.4GB discs however i may not always need 8.4GB so would the dual layer writer STILL write a normal 4.7GB disc. i then want to play this on a region free dvd player. this would work right??? thanks Dual layer writers will write single layer disks. thanks a lot
