DVD Writer only recognised as CD/DVD ROM in XP

Hi,

I am troubleshooting an RM Compal CY27 Laptop with XP Pro SP3 installed
as an OS. The CD Drive has been replaced with an Hitachi GSA-T40N
slimline drive which I have updated the firmware to JW02 (latest
available).

The issue is this, whilst Image Burn will find the drive and happily
burn CD's/DVD's (thus I know it works!!!) XP will only recognize the
drive as a DVD-RAM Drive and so all recording functions are absent.

On deeper analysis the Imapi service is missing from services altogether
and no appropriate registry entries are present. The 'filters' issue
widely reported does not apply as the registry entries reported (Upper &
Lower Filters) do not exist in the first place.

I have downloaded and installed Imapi V2.0 (for SP3) of microsoft but
the service stubbornly remains absent from the services list and so no
recording tab, no drag and drop to burn or other features are available.
I have also followed the ms kb articles on the subject to no avail
including the auto fix app provided by ms which simply reports that the
drive is not capable of burning!

Accordingly I am at a loss on this one as to why I cannot resolve what
on the face of it seems a simple issue and would welcome any pointers
you might offer as to what I need to do

Many thanks in advance.
