sardian and bighousie used our news submit to tell us that LiteOn has removed the latest firmware updates for their DVD burners LDW-411S and LDW-811S from their website. According to our drive reviewer OC-Freak, these firmwares had problems when writing to DVD+RW at 2.4x.
Unfortunately you will not be able to use the bitsetting tool with older firmwares. Our LiteOn Forum is the right place for you to discuss this topic.
