I'll agree with the retired Dragon and deanwitty. Slimline drives don't hold up real well. My wife got a cheap Wal-Mart Compaq lap-top 5 years ago and I had to try the burner. Burnt a DVD, it did a great job according to Disc Speed check. This has been the only burn it has done. It has read about 10 discs and all is good. The slim drives don't last very long with a lot of use. My DVD burning computer (for all video stuff) has 7 different burners and my workhorse, internet 'puter has one full size drive in it. Be aware DVD burners do have a duty cycle, that's why I have 7 drives in one computer. Each burn is done on a different drive , keeps the heat down of using just one drive.
