I have a CCD of Mars Matrix, 3 files, IMAGE.CCD, IMAGE.SUB, and IMAGE.IMG. But when I used Alcohol 120% to burn it, the resulting CD was unplayable on my dreamcast, making nasty scratching noises and such. I burned 3 CDs unsuccessfully. First try was RAW DAO, 4x speed. No dice. Second try was same settings, I thought it was a bad CD. Third try was RAW DAO, Rectify Sub-channel data option ON. Still the same effect as the previous two. What am I doing wrong?
