I'm one of those victims of Lite-On. They used to be awesome for cd rom drives but for some reason they've relied heavily on their past success to push a faulty product... I bought the DVD burner for like 60 bucks when dual layered burning came out.I heard Lite-On drives are loud and sucks at burning discs. You should consider LG or Samsung products.
Trust me avoid lite-on and choose either a Plextor or a NEC. I'd wait for some HD/BluR though.
