Memorex DVD Burner (Ricoh 5125A) Stopped working after XP install

Memorex-branded Ricoh MP5125A 2.4x single-layer DVD+R/RW under Nero 6 worked like a song.
I upgraded from 2000 Pro to XP Pro, now everything seems fine until I try to write and the drive will not recognize a blank DVD+R. 5125A is running firmware 1.72 (confirmed)
Nero Version Express (bundled)

Please help.

If you did an “upgrade install” as opposed to a clean install, this may only be the 1st of many issues. BTW, many folks consider XP a “downgrade” from 2K. :wink:

So which type of install did you do?

I did a clean install, new registry, new folder.
