After a recent m/b and OS upgrade, XP Pro hangs whenever I insert a disc into my Pioneer A-04. XP sees the drive in my computer, but with a CD/DVD in the drive, My Computer hangs until I eject the disc. Nero can't burn on it either. The A-04 is set as a slave on my secondary IDE, with a Sony CDRW and a generic DVD-ROM on my primary, both of which work properly. Any ideas?
