Samsung DVD/CD burning problems

hey, I have a Samsung DVD/CD SC-148C, and I was just wondering where I could get a brand-new set of drivers for it… it’s not burning or anything; it recognizes “full” dvd’s and cd’s, but not blank ones… another funny thing is that it only writes at speeds of up to 5x!!! and it’s a high speed drive… nearly brand-new, too… so I think it must be a software/driver problem. can someone help me out?
-thanks
:confused: :doh:

Is this a dvd burner or just a combo?
Drivers already come within the OS.
