Hi, I just bought a Benq Ew1621 external dvd burner. I installed it fine and the store clerk said I should be able to back up my movies in under an hour. Even burning avi files through nero take 11 hours, including 2 and a half hours burning time. Backing up dvds take 6 hours. I have USB 1.0, but that shoudlnt be a problem, Windows second edition and I'm not sure about anything else. If you have any ideas about what may be wrong just tell me. Also, if you have any questions, just ask.
