DVD DRIVE HELP!

[chillnow]

My dvd writer can read and write cds but cannot even read dvds. I have the region set as 5.
I have a philips dvd+rw d28 drive...just set it up. I'm running windows xp, 512 ram,i have nero installed.
I installed latest firmware. another version of the firmware i was trying to install but i got an error - ASPI manager not found. On net i found different variations of the wnaspi32.dll file(ASPI manager file), one is 49kb,other 200kb and another inside nero folder is 168kb.
Is it a software/driver problem??
Please help me,
thanks

as for windows 98

The four files needed for Win95/98/Me are the following:

WINDOWS\SYSTEM\IOSUBSYS\APIX.VXD
WINDOWS\SYSTEM\WINASPI.DLL
WINDOWS\SYSTEM\WNASPI32.DLL

and ONE of the following two files
WIN95\SYSTEM\ASPIENUM.VXD (if u r using Adaptec drivers)
WIN95\ASPI2HLP.SYS (if u r using default Win95 drivers)



The four files needed for WinNT/2K/XP are the following:

WINNT\SYSTEM\WINASPI.DLL
WINNT\SYSTEM\WOWPOST.EXE
WINNT\SYSTEM32\WNASPI32.DLL
WINNT\SYSTEM32\DRIVERS\ASPI32.SYS
