Have a slight problem, a old hitachi cdrewriter, apparently could write on rewritable disks and then they could be used on standard cdroms. But a new yamaha rewriter used rewriteable disks will not write disks that work on standard cdroms unless they are 32 - 36 speed. Is this correct or is there something else to be setup. plenty of points for this one as it's urgently required. oh, Merry Xmas and a Happy New Year to You.
