CD Writer in XP Pro

Hi

I have a LG 48x writer which was working perfectly fine with XP Home.

I recently upgraded to XP Pro and now the CD writer is not writing. It
reads fine. Is there any setting to be done for writing to work? Like any
service or DMA etc.

I am suspecting something like DMA cos it fails just after it starts
writing. I can make that out visibly from the blank CDR which then becomes
unusable.

Thanks for any help.
