Liteon 1633s

I was thinking about getting the Liteon 1633s any advice on this drive before
i buy

Why would you buy a 1633, this drive is almost not supported anymore by liteon. The latest firmware is dated december 04.
If you really want a liteon than get a 1673, or wait a little longer and get a 1693 !!!

What are your requirements for a DVD writer?
In terms of DVD writing quality, there are much better options out there instead of the 1633S.
