My Dimension 4700 *Medium* PC is configured with Windows-XP (Dell-delivered version) plus the followup Service Packs (SP).. Since I did install the SP2 & SP3 Windows-XP defines both DVD-RW drives (NEC-3450A, part of original delivery and Sony-DRU-710A, later installed) as DVD-ROM-drives, only!!!!!!!!! I did install all recent firmware updates for both units. So far, I did not find any specific DVD-RW driver for NEC and/or SONY drives.

What is wrong with my Windows-XP respectively what do I have to do to get Windows-XP to accept my drives as DVD-RW (Read/Write) units?
