XP not reconizing dvd drive

[Wadster]

Hi,
I have a new computer and have installed Xp pro with SP2. When installing i
got a few errors as follows: cannot copy the following files ks.sys, ps.sys
and modem.sys.
Then further down the installing track another file could not be installed
called wmpau8.wa_.
I chose to skip these errors as retry did nothing for me.
Anyway xp starts up fine. but it does'nt reconize the dvd drive. Computer
specs as follows. Any ideas?
P4 3.6 with HT
Mother Board ASUS p5gdv-V dulexe
DVD pioneer DVD-R109
hard drive WD200gb sata
1gb DDR2 ram
graphics card PCIex ati radeon X700

I would say remove SP2 and reinstall it
