Thanks John I have been on a voyage of discovery!

I have found in 'sound and audio devices' that I have:

ARTEC WRR-52Z (DVD/CD-R)
and
ATAPI 52xCDROM (DVD/CD-R)

Now, when I try to burn using nero, it does give me the option of choosing one of the above two drivers. I have tried both and neither will burn successfully, they both start fine then fail at about 10%.
Should I assume that because I am trying to burn audio cd that I should only be using the ARTEC one, because the ATAPI one has CDROM written by it?

Also why does Real one player kick in when I try to burn? Should it be doing that? If I uninstalled real one player would everything go kaput?
