Then I suggest you add CloneCD (doesn't need ASPI) and CDRWin (needs ASPI) to your collection and try them. I use all three (inc. Nero) and they all coexist happily. If either of the other two work, then we have narrowed the problem down to NERO and perhaps that'll work too after layers for CDRWin have been installed.

If CDRWin doesn't work, then install the ASPI layer on www.goldenhawk.com and try both CDRWin and Nero again.

Keep us posted.
