Ain't the original DVD-RAM discs (2.6Gb and 5.2Gb) simply based on Sony's M.O. discs (by making then write optically). fusk Sony for trying to screw up DVD. Now thanks to those motherf.....s we have a (practically) propietory format, and they're pushing it as a standard.
nobody is going to accept DVD-RAM as a standard, it's just not practical when compared to DVD-R and DVD+R formats.. DVD-RAM will eventually fade away.
