Liteon SHOW -1653s


I bought yesterday a LITEON SHOW-1653s.
Now my problem is that he do not see any of my DVD-roms.
I Already tryed Verbatim DVD+R Verbatim DVD-R, Princo DVD-R. Every time when I try to burn something Nero of wathever says that there is No Medium in my DVD RW. It seems like MY Liteon don’t see any of my DVD’s
What should I do?

Did you check the obvious that you have the correct master and slave settings? Or tried a new IDE cable? and if that doesn’t work return it for a new one.
