My notebook has an Optiarc AD-7561S burner inside. I want to use this burner to burn a DL disk, which has to be bitset to DVD-ROM. I tried this with DVDInfoPro, but it seems to bitset DVD+R (not DL) only. I also tried ImgBurn, but that didn't work either. Do you have any other ideas that might help me? Or is it simply not possible to do?
