I have succeeded in doing this by using Player:

Download the details from Cddb using Player, which has an option to export details to windows/cdplayer.ini. Orange CD has an option to import from there. This works!

NB If OrangeCD has previously saved the details of the disc not found on freedb under "New Artist" or some such, this will block the import of new details from cdplayer.ini. You will need to delete this entry.
