As you have mentioned, you can calculate the layer break when making an .iso first. That's the advantage. So the question is more is there a disadvantage. :bigsmile:
I would carefully say there is none. But I can't say anything about CopyToDVD. If it makes perfect .iso-files - and why shouldn't it make perfect ones, that's not a very complex function - then there shouldn't be one.
AS: I use EMC9 and it shows the Plextor specific features like PowerRec. AS I'm not sure right now. But anyway, normally the LED is flashing in 3 different colors when AS is creating a new strategy. You could watch the LED while forcing a new strategy. But isn't AS independent from outside burning software commands anyway?
I hope better help by other members is on the way...
