I've use "creator classic" application of Roxio. I just want to burn a dvd like that because of the size. Other dvd's can left open to burn new items later. But a double layer had to be closed. But even that was't good enough to burn it, 'cause after 1 minute the program stopt an show an error that the double layer could't be burn.
I start with 5Gb burning, an had in mind to add more later. I did burn a large movie to a double layer before,but at that time I used the dvd burn program from Windows 7 pro, without any problems. I was very surprised Roxio couldn't do the job.
