This may sound stupid, I've searched online and found nothing relating to my problem.
I've been burning disks for years, always the same type of disk, DVD+R. I have hundreds of disks burnt with data, movies everyting. So I know there's no problem with the disks, there was no problem with my hardware. Only yesterday I succesfuly burnt 2 data disks. Today however I start "roxio" to burn another data disk and now it tells me my drive cant record on "+" disks and I should insert a "-" disk.
What the hell is the problem?
