Sorry for delay - boots hard to get on!
Have just checked out both programs. Very odd.
Feurio creates .cdc files and they can be used as input for Feurio or Nero's Cover design programs. Very flexible.
Nero does not appear to create .cdc but only .nra. No problem so far. However, if you have a multi-disk set in Nero, in order to automatically populate labels of disks 2 and upwards, you seem to have to import .cdc files. No facility for .nra import.
I must be missing something.
Thanks for info.
