Avoid Liteon, IMO. Mine died the day after the warranty expired, no recourse. Interesting, though, my newer PC Sony DVD burner is a rebranded Liteon. It works great.
Replaced it with a Samsung which died after 10 hours.
Bit the bullet and got a much more expensive Sony with a 3 year extended warranty and of course, I haven't had any problems.
I'm finished with buying cheap equipment. There is a lot of it out there. You get what you pay for.
