My DVD-RW drive cannot be detected in my video editing software (Pinnacle Studio 11), I have looked in Device manager and it seems to be there and all the drivers are updated.
Does it work in terms of reading disks? Try updating the firmware for it either via your pc manufacuter's support site or head to the drive maker's support site.
Go to the pinnacle site and look for software update. Windows XP has that problem in Vista or 7 no problem. I have also tried downloading something on the microsoft site for this problem but I don't remember the link (sorry).
In Windows XP I remember un installing the device (DVD) then let Windows detect and install it and it worked.
