Hello my friend, Thus you Disk Rom is a DVD? if it not DVD then it cannot read DVD but if it is DVD then try to insert other DVD or CD Disk to check if it really works. Also try to clean your ROM with a disk cleaner. Then if all of the steps are done and still the result is same problem then ship it back to the suplier or buy new ROM. Thanks
