I am going to buy a dvd burner and do not know which one to get. I am going to use it to backup games and movies and games so the originals do not get ruined by my 4 year old. I have a liteon ldw 811s and it has failed miserably. i have made at least 50 coasters and I am not interested in liteon at all. i want a dvd burner to put in my BYTECC external USB2 enclosure for my laptop and have been looking at the nec 3540a and the benq 1640. if someone knows of a better burner plese let me know as I must buy one in the next few days. any help is appriciated.
