If I remember well it's a bug in CDSpeed's "create disc" feature with version 220.127.116.11, will always burn at max with some burners, whatever the burning speed selected.
If you burn with IMGburn, Nero or another burning app, your 42N will obey you.
No it's not. :rolleyes: - since when is it normal to have 18X burning when selecting 8X or 16X? :bigsmile:
